APW7328

APW7328 3.5A, 5V, 1.2MHz Synchronous Step-Down Converter Features General Description 3.5A Continuous Output Current Operating Voltage Range : 2.7V~5.5V Fixed Switching Frequency : 1.2MHz (PWM) 0.6V Reference Voltage PSM/PWM Operation Low RDS(ON) Internal Power MOSFETs OCP Protection and Thermal Shutdown Internal Compensation Short Circuit Protection with Hiccup mode Fold-back Switching Frequency Over Temperature Protection Input Over Voltage Protection TQFN2x2-12A package Lead Free and Green Devices Available (RoHS Compliant) Simplified Application Circuit The APW7328 is a high efficiency monolithic synchronous buck converter. APW7328 operates with a constant 1.2MHz switching frequency and using the inductor current as a controlled quantity in the current mode architecture. The 2.7V to 5.5V input voltage range makes the APW7328 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable electrical devices. The internally fixed 1.2MHz operating frequency allows the use of small surface mount inductors and capacitors.
