XL6109 Overview
Description
XL6109 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.
