Product Overview

The ADP2107ACPZ-R7 is a synchronous step-down DC-to-DC Converter for use with set-top boxes. At medium to high load currents, this device uses a current-mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response. To ensure the longest battery life in portable applications, the ADP2107 uses a pulse frequency modulation (PFM) control scheme under light load conditions that reduces switching frequency to save power. The ADP2107 run from input voltage of 2.7 to 5.5V, allowing single Li+/Li- polymer cell, multiple alkaline/NiMH cells, PCMCIA and other standard power sources. The output voltage of ADP2107 is adjustable from 0.8V to the input voltage (indicated by ADJ). The power switch and synchronous rectifier are integrated for minimal external part count and high efficiency. During logic controlled shutdown, the input is disconnected from the output and it draws less than 0.1µA from the input source.
  • Extremely high 97% efficiency
  • 100% Maximum duty cycle
  • Smoothly transitions into low dropout (LDO) mode
  • Internal synchronous rectifier
  • Optimized for small ceramic output capacitors
  • Enable/shutdown logic input
  • Undervoltage lockout
  • soft-start
  • 20μA Ultralow quiescent current
  • 0.1μA Shutdown supply current
