PS5005
High Efficiency, Low Voltage Step-up DC/DC Converter
GENERAL DESCRIPTION
The PS5005 is a compact, high efficiency, and low voltage step-up DC/DC converter with an Adaptive Current Mode PWM control loop.
It comprises of an error amplifier, a ramp generator, a PWM comparator, a switch pass element and the driver.
It provides stable and high efficient operation over a wide range of load currents without external compensation.
The below 1V start-up input voltage makes PS5005 suitable for single battery cell applications.
The built-in power
transistor is able to provide up to 300mA output current while working under Li-Battery Supply.
Besides, it provides extra pin to drive external power ...
