Product Overview

The ADP2119ACPZ is a synchronous step-down DC-to-DC Regulator for use with point of load conversion. It uses a current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response. Under light load conditions, they can be configured to operate in a pulse frequency modulation (PFM) mode, which reduces switching frequency to save power. The ADP2119 support input voltage from 2.3 to 5.5V. The ADP2119 require minimal external parts and provide a high efficiency solution with their integrated power switches, synchronous rectifiers and internal compensation. Each IC draws less than 2µA current from the input source when it is disabled. Other key features include undervoltage lockout (UVLO), integrated soft-start to limit inrush current at startup, overvoltage protection (OVP) and overcurrent protection.
  • Current-mode architecture
  • Precision threshold enable input
  • Power-good flag
  • Voltage tracking
  • Integrated soft-start
  • Internal compensation
  • Startup with precharged output
  • Synchronizable between 1 and 2MHz
  • 145 and 70mR Integrated MOSFETs
  • ±1.5% Output accuracy
