2 AMP ADJUSTABLE POSITIVE STEP-DOWN

INTEGRATED SWITCHING REGULATOR PT6310

  • 87% Efficiency
  • Adjustable Output Voltage
  • Internal Short Circuit Protection
  • Over-Temperature Protection
  • On/Off Control (Ground Off)
  • Small SIP Footprint
  • Wide Input Range The PT6310 series is a High- Performance 2 Amp, 12-Pin SIP (Single In-line Package) Integrated Switching Regulator (ISR) designed to meet the on-board power conversion needs of battery powered or other equip- ment requiring high efficiency and small size. This high perfor mance ISR offers a unique combination of features combining 87% typical efficiency with open-collector on/off control and ad- justable output voltage. Quiescent current in the shutdown mode is typically less than 100µA. Standard Application C1 = Optional 1µF ceramic C2 = Required 100µF electrolytic Q1 = NFET
