Product Overview

ST1S10PHR is a high-efficiency step-down PWM current mode switching regulator capable of providing up to 3A of output current. This device operates with an input supply range from 2.5V to 18V and provides an adjustable output voltage from 0.8V (VFB) to 0.85VIN_SW [VOUT = VFB (1 + R1/R2)]. It operates either at a 900KHz fixed frequency or can be synchronized to an external clock (from 400KHz to 1.2MHz). The high switching frequency allows the use of tiny SMD external components, while the integrated synchronous rectifier eliminates the need for a Schottky diode. It provides excellent transient response and is fully protected against thermal overheating, switching overcurrent and output short-circuits. Applications include consumer, networking, computer, industrial, and security.
  • Step-down current mode PWM regulator, output voltage adjustable from 0.8V
  • Input voltage from 2.5V up to 18V, 2% DC output voltage tolerance
  • Synchronous rectification, inhibit function
  • Synchronizable switching frequency from 400KHz up to 1.2MHz
  • Internal soft start, dynamic short-circuit protection
  • 90% typical efficiency at (OUT = 300mA to 3A)
  • Output current is 3A minimum at (VIN = 2.5V to 18V VOUT = 0.8V to 13.6V)
  • Quiescent current is 1.5mA typical at (VINH > 1.2V, not switching)
  • Feedback voltage is 800mV typical at (TJ = 25°C)
  • Operating junction temperature range from -40°C to 125°C, PowerSO-8 package
