APW7199 - High-Performance Step-Down PWM Controller

Description

The APW7199 is a single-phase, constant-on-time, and synchronous P WM controller, which drives N-channel MOSFETs.

An internal 0.5V temperature-compensated reference voltage with high accuracy is designed to meet the requirement of low output voltage applications.

Features

  • Operates from An Input Battery Voltage Range of +3V to +25V ±0.6% 0.5V Reference - Over Line, Load Regulation, and Operating Temp. Drive Dual Low Cost N-Channel MOSFE Ts - Adaptive Shoot-Through Protection Power-On-Reset Monitoring on VCC Pin PFM Mode for Increasing Light Load Efficiency Constant-On-Time Control Scheme - Switching Frequency Compensation for PWM Operation General.
