NR264S Overview
Key Specifications
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.
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)
