Overview
APW7037A/B 8-PIN Synchronous Buck PWM Controller Features General Description • Operating with Single 5V or 12V Input • Drives N-Channel MOSFETs • Simple Single-Loop Control Design - Voltage-Mode PWM Control - Full 0% to 100% Duty Ratio - Fast Transient Response • ±2% Output Voltage Accuracy Over Temperature • Under-Voltage Protection for Output • 200/400kHz Constant Frequency Operation - 200kHz for APW7037B - 400kHz for APW7037A • Small size, 8-PIN Package (SOIC or TSSOP) • Lead Free and Green Devices Available (RoHS Compliant) The APW7037 series are designed to provide a low cost synchronous Buck regulator for on-board DC to DC converter applications.
The APW7037 series together with dual N-channel MOSFETs such as APM7313, provide a low cost solution for such applications.
Each device features an internal 200/400kHz oscillator, Power-On-Reset (POR) for both VCC and VC supplies, an external programmable soft-start function as well as output undervoltage detection that latches off the device when an output short is detected.
