Additional Information

High Efficiency Switching Regulators

Features:
- Wide Input Voltage Range 3V to 60V
- Low Quiescent Current—6mA
- Internal 1.25A Switch
- Very Few External Parts Required
- Self-Protected Against Overloads
- Operates in Nearly All Switching Topologies
- Shutdown Mode Draws Only 50μA Supply Current
- Flyback-Regulated Mode has Fully Floating Outputs
- Can be Externally Synchronized

Typical Electrical Characteristics
(Full Operating Temp. ; VIN = 15V, VC = 0.5V, VFB = VREF, output pin open unless otherwise noted):

Reference Voltage (Measured at Feedback Pin, VC = 0.8V): 1.244V
Feedback Input Current (VFB = VREF): 1100nA max.
Error Amplifier Source or Sink Current (VC = 1.5V): 400uA max.
Supply Current (3V ≤ VIN ≤ VMAX ; VC = 0.6V): 6mA
Output Switch ON Resistance (ISW = 1.25A): 0.6Ω
Maximum Switch Duty Cycle: 92%
Flyback Sense Delay Time: 1.5us

Applications:
- Logic Supply 5V at 2.5A
- 5V Logic to ±15V Op Amp Supply
- Offline Converter up to 50W
- Battery Upconverter
- Power lnverter (+ to –) or (– to +)
- Fully Floating Multiple Outputs
- Driver for High Current Supplies
