NR111D
Overview
The NR111D is a buck converter IC that integrates the power MOSFET. With the current mode control, ultra low ESR capacitors such as ceramic capacitors can be used.
- Up to 94% Efficiency Up to 68% Efficiency at Maximum at Light Load (IO = 20 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 Undervoltage Lockout (UVLO)
