SP6153 - 300kHz Synchronous Buck Controller

Description

The SP6153 has been designed to be implemented as synchronous step-down switching regulator.

A complete high performance supply using Type III compensation can be created with as few as 11 external components.

Compensation has been optimized based on output voltage and output capacitor selection.

Features

  • 4.5V → 30V Input step down converter.
  • Built-in feedback compensation with feed forward.
  • Overcurrent circuit protection with auto-restart using FET RDSon sensing.
  • 300kHz fixed switching frequency.
  • External synchronization capable.
  • Up to 30A output capability.
  • Highly integrated design, minimal components.
  • UVLO detects both VCC and VIN.
  • Power Good and Fault Output.
  • On-board 1Ω sink (1.5Ω source) NFET drivers.
