ST1S10PHR ST DC-DC Converters

The ST1S10PHR is a high-efficiency step-down current-mode PWM switching regulator from STMicroelectronics in an SOIC-8 package, capable of delivering up to 3A output current from an input supply range of 2.5V to 18V . For selection, verify output voltage adjustable from 0.8V to 15.3V using external resistors, confirm switching frequency fixed at 900kHz (synchronizable from 400kHz to 1.2MHz), note 90% typical efficiency, quiescent current of 1.5mA typical (6µA max in standby), and operating temperature from -40°C to +125°C . Features include synchronous rectification eliminating external Schottky diode, internal soft-start, inhibit function for power sequencing, dynamic short-circuit protection, and thermal shutdown. Ideal for consumer electronics (set-top boxes, DVD recorders, LCD TVs, car audio), networking (xDSL modems, DC-DC modules), computer peripherals (printers, hard drives, audio/graphic cards), industrial and security applications (battery chargers, DC-DC converters, FPGA/PLD power supplies, LED drivers) .
