The AP9266 is a compact, high-efficiency,
step-up DC/DC converter that operates from an
input voltage as low as 1Volt. The low start-up
input voltage makes the device suitable for 1 to 4
battery cell applications delivering up to 400mA
load current.
AP9266 features a voltage mode PWM control
loop, providing stable and high-efficiency
operation over a broad load current range without
external compensation. High frequency 550KHz
switching allows the use of small size external
components.
The 2.5V to 6V output voltage is set with 2
external resistors. Both internal 2A NMOS power
switch and driver or external power switch
(NMOS or NPN) are provided for design flexibility.
The device is available in SOT-23-6 package
