NR110K - Buck Converter

Description

The NR110K is buck converter ICs that integrate the 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 Overcurrent Protection (OCP), Under-Voltage Lockout (UVLO) and Thermal Shutdown (TSD).

Features

Up to 90% Efficiency (VIN = 12 V, VO = 5 V, IO = 1 A) Up to 70% Efficiency at Maximum at Ligh Load (VIN = 12 V, VO = 5 V, IO = 30 mA).
Current mode PWM control.
Stable with Low ESR Ceramic Output Capacitors.
No External Components Required by Incorporating Phase Compensation.
Soft-Start Function Adjustable Soft-Start time with an External Capacitor.
External ON/OFF Function.
Protection Functions:.
Overcurrent Protection (OCP): Drooping, auto-restart Therm.

4 A, 31 V, 350 kHz, Buck Converter NR110K Data Sheet Description The NR110K is buck converter ICs that integrate the 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 Overcurrent Protection (OCP), Under-Voltage Lockout (UVLO) and Thermal Shutdown (TSD). An adjustable Soft-Start by an external capacitor prevents the excessive inrush current in startup. The feature increasing efficiency at light loads allows the device to be used in the energysaving applications. The ICs integrate phase compensation circuit which reduces the number of external components and simplifies the design of customer application.
