G5601A - High-Speed Step-Down Controller

Download the G5601A datasheet PDF. This datasheet also covers the G5601A-GlobalMixed variant, as both devices belong to the same high-speed step-down controller family and are provided as variant models within a single manufacturer datasheet.

General Description

G5601A 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.

Key Features

  • --PWM Controller.
  • 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.
  • 4.5V to 24V Battery Input Range.
  • OVP & UVP.
  • 1.7ms Soft-Start.
  • Drives Large Synchronous-Rectifier FETs.
  • Power-Good Indicator --LDO Controller.
  • 1.5% Accuracy Over Line and Load.
  • Adjustable Ou.
