• Soft Start

The FAN5307, a high efﬁciency low noise synchronous

PWM current mode and Pulse Skip (Power Save) mode

DC-DC converter is designed for battery-powered applica-

tions. It provides up to 300mA of output current over a wide

input range from 2.5V to 5.5V. The output voltage can be

either internally ﬁxed or externally adjustable over a wide

range of 0.7V to 5.5V by an external voltage divider. Custom

output voltages are also available.

• Dynamic Output Voltage Positioning

• 15µA Quiescent Current

• Excellent Load Transient Response

• 5-Lead SOT-23 Package

At moderate and light loads pulse skipping modulation is

used. Dynamic voltage positioning is applied, and the output

voltage is shifted 0.8% above nominal value for increased

headroom during load transients. At higher loads the system

automatically switches to current mode PWM control,

operating at 1 MHz. A current mode control loop with fast

transient response ensures excellent line and load regulation.

In Power Save mode, the quiescent current is reduced to

15µA in order to achieve high efﬁciency and to ensure long

battery life. In shut-down mode, the supply current drops

below 1µA. The device is available in 5-lead SOT-23 and

6-lead MLP 3x3mm packages.

• 6-Lead MLP 3x3mm Package

Applications

• Pocket PCs, PDAs

• Cell Phones

• Battery-Powered Portable Devices

• Digital Cameras

• Low Power DSP Supplies
