General Description

XL6108 is a built in high frequency power

transistor and Schottky diode Boost DC/DC

converter, fixed 1.2MHz frequency PWM,

can support input operating voltage range of

2.5V~25V, built in frequency compensation

circuitry allows the use of small external

components at a price suitable for lowering

the cost of the entire power supply system

and reduce the printed circuit board space.

The output voltage is adjustable by external

divider resistors, and the low feedback

voltage of 410mV reduces the power

consumption of the external sampling

resistors, the EN pin supports TTL ON/OFF,

and the built in output overvoltage protection

and thermal shutdown protection. Suitable

for very low quiescent current and ultrasmall size applications.

Applications

? PanelPower Supply

? GPS Receiver

? DSL modem

? Wearable portable electronic devices
