产品信息
产品概述
ST1S50PUR is a 4A monolithic synchronous step-down switching converter with high efficiency at light load. The ST1S50 device is a 500KHz fixed frequency PWM synchronous step-down regulator. The ST1S50 operates from 4.0V to 18V input, while it regulates an output voltage as low as 0.8V and up to 0.88 x VIN. The ST1S50 device integrates a 95mohm high-side switch and a 69mohm synchronous rectifier allowing very high efficiency with very low output voltages. The peak current mode control with a special PFM mode enables high efficiency at a light load. Typical applications include point of load for: STB, TVs, gateway, solid state disk drive, Blu-ray, DVD, µP/ASIC/DSP/FPGA core and I/O supplies.
- Output voltage adjustable from 0.8V to 0.88 x VIN
- High efficiency at light load
- Programmable soft-start and enable
- All ceramic capacitor
- Cycle-by-cycle current limiting
- Short-circuit protection
- Available in 10 pin VFDFPN package
