General Description
The NR264S is synchronous rectification buck converter IC with built-in power MOSFET.
In light load, the IC operates with the pulse skip mode to improve the efficiency.
By using the peak current control method, the IC stably operates with a low ESR capacitor such as a ceramic capacitor.
Key Features
- Synchronous Rectification.
- Operation Modes: Normal Load: Current Mode PWM Control Light Load: Pulse Skip Operation.
- Maximum Efficiency (VIN = 12 V, VOUT = 5 V) Normal Load: 94% Light Load (IOUT = 10 mA): 86%.
- Stable with a Low ESR Ceramic Output Capacitor.
- Soft-start Period Adjustment by External Capacitor.
- Enable Function.
- Frequency Limitation Function (Pulse Skip Frequency in Light Load is Limited to 28 kHz).
- Protections: Overcurrent Protection (OCP): D.
