NR121E - SANKEN

NR121E 3A 18V Buck Regulator

The NR120E series is buck regulator ICs integrates High-side power MOSFET. With the current mode control, ultra low ESR capacitors such as ceramic capacitors can be used. The ICs have protection functions such as Over-Current Protection (OCP), Under-Voltage Lockout (UVLO) and Thermal Shutdown (TSD). An adjustable Soft-Start by an external capacitor prevents.
