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 excess.
● 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
Thermal Shutdown (TSD): Auto-restart Under Voltage Lockout (UVLO)
