ST1S10PHR Description
The ST1S10PHR is a high efficiency step-down PWM current mode switching regulator capable of providing up to 3 A of output current. The ST1S10PHR device operates either at a 900 kHz fixed frequency or can be synchronized to an external clock (from 400 kHz to 1.2 MHz). The high switching frequency allows the use of tiny SMD external components, while the integrated synchronous rectifier eliminates the need for a Schottky diode. The ST1S10 provides excellent transient response, and is fully protected against thermal overheating, switching overcurrent and output short-circuit. The ST1S10PHR is the ideal choice for point of load regulators or LDO pre-regulation.
ST1S10PHR Features
● Step-down current mode PWM regulator
● Output voltage adjustable from 0.8 V
● Input voltage from 2.5 V up to 18 V
● 2% DC output voltage tolerance
● Synchronous rectification
● Inhibit function
● Synchronizable switching frequency from 400 kHz up to 1.2 MHz
● Internal soft start
● Dynamic short-circuit protection
● Typical efficiency: 90%
● 3 A output current capability
● Standby supply current: max. 6 μA over temperature range
● Operative junction temp.: from -40 °C to 125 °C
ST1S10PHR Applications
● Consumer
◆ STB, DVD, DVD recorders, TV, VCR, car audio, LCD monitors
● Networking
◆ XDSL, modems, DC-DC modules
● Computer
◆ Optical storage, HD drivers, printers, audio/graphic cards
● Industrial and security
◆ Battery chargers, DC-DC converters, PLD, PLA, FPGA, LED drivers
