Anpec Electronics APW7120A
The APW7120A is a fixed 300kHz frequency, voltage mode, and synchronous PWM controller. The device drives two low cost N-channel MOSFETs and is designed to work with single 5~12V or two supply voltage(s), providing excellent regulation for load transients. The APW7120A integrates controls, monitoring and protection functions into a single 8-pin package to provide a low cost and perfect power solution.| Part No. | APW7120A |

FEATURES
GENERAL DESCRIPTION
● Operating with Single 5~12V Supply Voltage or Two Supply Voltages● Drive Dual Low Cost N-Channel MOSFETs - Adaptive Shoot-Through Protection
● Built-in Feedback Compensation - Voltage-Mode PWM Control - 0~100% Duty Ratio - Fast Transient Response
● ±2% 0.8V Reference - Over Line, Load Regulation, and Operating Temperature
● Programmable Over-Current Protection - Using R of Low-Side MOSFET DS(ON)
● Hiccup-Mode Under-Voltage Protection
● 118% Over-Voltage Protection
● Adjustable Output Voltage
● Small Converter Size - 300kHz Constant Switching Frequency - Small SOP-8 Package
● Built-In Digital Soft-Start
● Shutdown Control Using an External MOSFET
● Lead Free and Green Devices Available (RoHS Compliant) A power-on-reset (POR) circuit monitors the VCC supply voltage to prevent wrong logic controls. An internal 0.8V reference provides low output voltage down to 0.8V for further applications. An built-in digital soft-start with fixed soft-start interval prevents the output voltage from overshoot as well as limiting the input current.
