Overview
Buck type Synchronous Switching Regulator IC NR421A DATA SHEET General Descriptions The NR421A is Synchronous Rectification buck regulator ICs integrates PowerMOSFETs.
With the current mode control, low ESR capacitors such as ceramic capacitors can be used.
It has achieved a high efficiency by the synchronous rectification system.
The ICs have protection functions such as Over-Current Protection (OCP), Under-Voltage Lockout (UVLO) and Thermal Shutdown (TSD).
Soft starting time can be set up by selecting an external capacitor value.
The ON/OFF pin (EN Pin) turns the regulator ON/OFF.
The NR421A is available in an 8-pin HSOP package with an exposed thermal pad on the back side.
