- High efficiency
- Uses readily available standard inductors
- Thermal shutdown and current limit protection
- P+ Product Enhancement tested

Typical Electrical Characteristics (TJ=25°C unless otherwise noted):
Output Voltage
- VIN = 12V, ILOAD = 0.2A: 5.0V typ.
- 0.2A ≤ ILOAD ≤ 1A,8V ≤ VIN ≤ 40V: 5.0V typ.
Efficiency (VIN = 12V, ILOAD = 1A): 77%
Oscillator Frequency: 52kHz
Saturation Voltage (IOUT = 1A): 0.9V
Max Duty Cycle (ON): 98%
Current Limit (Peak Current): 2.2A
Output Leakage Current (Output = -1V): 7.5mA
Quiescent Current: 5mA
