Features & Applications
The ST1S40IDR is an internally compensated 850 kHz fixed-frequency PWM synchronous stepdown regulator. Available in a SOIC-8 package.
The ST1S40 integrates a 95 mΩ high side switch and 69 mΩ synchronous rectifier allowing very high efficiency with very low output voltages.
Features:
- 3 A DC output current
- 4.0 V to 18 V input voltage
- Output voltage adjustable from 0.8 V
- 850 kHz switching frequency
- Internal soft-start
- Integrated 95 mΩ and 69 mΩ Power MOSFETs
- All ceramic capacitor
- Enable
- Cycle-by-cycle current limiting
- Current fold back short-circuit protection
Applications:
- μP/ASIC/DSP/FPGA core and I/O supplies
- Point of load for: STB, TVs, DVD
- Optical storage, hard disk drive, printers, audio/graphic cards
