APW7075
Step-Up Converter and LDO Combo
Features
General Description
• Built-In a 500mA LDO and Synchronous Step-Up The APW7075 is a PWM/PFM, high-efficiency, and step-
DC-DC Converter
• Built-In PWM/PFM Operating Mode
up DC-DC converter with an integrated LDO input switch for dual mode application. During battery mode operation, the APW7075 acts as synchronous rectifier and step-up
• Provided Dual Input Power Sources • Connect FB to OUT for 3.3V Output Voltage or
DC-DC converter with a fixed or adjustable output voltage. When the VIN pin sense 5V input voltage, the APW7075 is switched to LDO operation mode, maintaining the con-
GND for 2.5V Output Voltage or an External
stant output voltage.
Resistor Divider for Adjustable Output Voltage. The input voltage ranges from 0.
