G5617B - Programmable Output High-Speed Step-Down Controller

This page provides the datasheet information for the G5617B, a member of the G5617A-GlobalMixed Programmable Output High-Speed Step-Down Controller family.

Description

G5617A/G5617B PWM controller uses constant on-time control scheme to handle wide input/output voltage ratios with ease and provides 100ns “instant-on” response to load transients while maintaining a relatively constant switching frequency.

Features

  • Ultra-High Efficiency.
  • No Current-Sense Resistor (Lossless ILIMIT).
  • Quasi-PWM with 100ns Load-Step Response.
  • 1% VOUT Accuracy Over Line and Load.
  • 0.75V to 3.6V Adjustable Output Range.
  • Dynamic Voltage Scaling by G0 and G1 Inputs.
  • 4.5V to 24V Battery Input Range.
  • OVP & UVP.
  • Built-in BST Diode.
  • 1.7ms Soft-Start.
  • Drives Large Synchronous-Rectifier FETs.
  • Power-Good Indicator.
  • G0/G1 H.
