Datasheet Summary
High Efficiency, Low Voltage Step-up DC/DC Converter
GENERAL DESCRIPTION
The PS5005 is a pact, high efficiency, and low voltage step-up DC/DC converter with an Adaptive Current Mode PWM control loop. It prises of an error amplifier, a ramp generator, a PWM parator, a switch pass element and the driver. It provides stable and high efficient operation over a wide range of load currents without external pensation. 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...
