CS7D6381

Prelim A. Jan 2012

General Description

The CS7D6381 is a high efficiency PFM step-up DC-DC converter with low ripple output in small SOT-23-3/5 package. The device consists of an oscillator, a PFM control circuit, a driver transistor, a driving transistor switching protection circuit, a reference voltage unit, and a high speed comparator. Only three external com-ponents are required to provide a fixed output voltage with ±2.5% accuracy. The pulse frequency modulation (PFM) step-up circuit requires a minimum supply current and achieves a small output ripple at light output loading. The device features extremely low start-up voltage and CMOS technology ensures low supply current which are ideal for battery-operated applications powered from one or more cells. The optional build-in enable function of the devices ensures low power consumption during shutdown mode.

CS7D651E Positive and Negative Output DC-DC Controller

General Description The CS7D651E is a dual-output DC-DC converter generating independent adjustable positive and negative output voltages. The CS7D651E can operate from 2.7V to 5.5V to generate a positive voltage up to +15V and a negative voltage down to -15V. The CS7D651E operates in fixed frequency PWM control topology and de-signed with power-save mode control. In typical operation, the conversion efficiency of the positive side and negative side can reach 85% and 81%, respectively. The CS6D651E has a built-in switching power MOSFET that can output more than 1A output current in typical applications (input voltage to output voltage ratio de-pendent). The CS7D651E consumes 500uA quiescent current in normal operation. In shut-down mode, the current consumption can be further reduced to 1uA. The CS7D651E is equipped with separate power-save mode control pins and enable pins to entertain the needs of different power management solution. The high efficiency and low current consumption design of CS7D651E enables it to be powered-up directly by battery. It further equips with separate control pin which can support the use of external power switch to disconnect the CS7D651E from the battery directly. The CS7D651E is packed in a 4mm x 4mm VQFN-24 package, together with internal thermal and overcurrent protection, which promotes the seamless integration of the chip to space sensitive application with highest reliability.

1.5MHz, 1A, High Efficiency PWM Step-Down DC/DC Converter

General Description CS7D8016 is a high-efficiency monolithic synchronous pulse-width-modulated (PWM) step-down DC-DC con-verter. The internal power switches can provide 1A continuous load current over the input range from 2.5V to 5.5V without the need of external Schottky diode, which make CS7D8016 perfectly suitable for the application of 1-cell Li-ion battery powered space limited appliances, such as cellular phones, PDAs and hand-held devic-es. CS7D8016 can operate in normal PWM mode or low droupout mode automatically to adjust the on-resistance of the power switches such that to provide a stable regulated output voltage according to the load-ing requirement. The CS7D8016 will enter shutdown mode and consumes less than 0.1uA when EN pin is pulled low. Both fixed output voltage (1V to 3.3V with 0.1V per step) or adjustable output voltage (through ad-justment of output resistor network) types are available, The switching ripple is easily smoothed-out by small package filtering elements due to a fixed operating frequency of 1.5MHz. This along with small WDFN-6L 2x2 package provides small PCB area application. Other features include soft start, lower internal reference volt-age with 2% accuracy, over temperature protection, and over current protection.

Universal High Brightness LED Driver

General Description The CS7D9910 is an open loop, current mode, buck converter based LED driver. The device operates in open loop mode control and thus can achieves good output current regulation without the need for any loop com-pensation. It requires only three external components (apart from the power stage) to product a controlled LED current making it an ideal solution for low cost LED drivers. The device can operate in either constant off-time or constant frequency mode. An internal 8 ~ 450V linear regulator allows the device to work with a wide input voltage range without the need for an external low voltage supply. A PWM output enable pin allows 0 ~ 100% duty ratio control. The PWM output enable pin can accept signal with frequency up to a few kilohertz, and thus can function as electronic dimming control without any flickering problem. Another linear dimming control pin allows a 0 ~ 250mV input to control the PWM duty cycle and thus linearly control the LED current. The PWM dimming response is limited only by the rate of rise and fall of the inductor current.

Features High efficiency 90% (Typ.) 1.2MHz switching frequency operation Input voltage range 8 ~ 450V Internal high voltage linear regulator

General Description

The CS7D9350 is capable of driving single or multiple series connected LEDs efficiently from a voltage source higher than

the LED voltage. This step-down converter provides an externally adjustable output current of up to 350mA from an input

supply between 7V and 32V. It can even reach 8 watts of output power, depending on supply voltage and external compo-

nents.

The CS7D9350 consists of an output switch and a high-side output current sensing circuit that uses an external resistor to

set the nominal average output current. Through applying an external control signal to the ‘ADJ’ pin, it can adjust the output

current to above or below the set value. The ‘ADJ’ pin will accept either a DC voltage or a PWM waveform to provide a con-

tinuous or a gated output current.

General Description The CS7D9360 is a continuous mode inductive step-down converter, designed for driving single or multiple series connect-ed LEDs efficiently from a voltage source higher than the LED voltage. CS7D9360 operates from an input supply between 6V and 40V and provides an externally adjustable output current of up to 1A. Depending upon supply voltage and external components, this can provide up to 40 watts of output power. The CS7D9360 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current. Output current can be adjusted above, or below the set value, by applying an exter-nal control signal to the ‘ADJ’ pin. The PWM filter provides a soft-start feature by controlling the rise of input/output current. The soft-start time can be in-creased using an external capacitor from the ADJ pin to ground. Applying a voltage of 0.2V or lower to the ADJ pin turns the output off and switches the device into a low current standby state.
