NR117K
Overview
The NR117K 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.
- Up to 87% Efficiency (VIN = 12 V, VOUT = 5 V, IOUT = 0.3 A) Up to 68% Efficiency at Maximum at Ligh Load (VIN = 12 V, VOUT = 5 V, IOUT = 10 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
- Frequency: 30 kHz (EMI considered)
- Protection Functions:
- Overcurrent Protection (OCP): Drooping, auto-restart Thermal Shutdown (TSD): Auto-restart Under Voltage Lockout (UVLO)
