LSP5503L - 3A 23V Synchronous Buck Converter

Download the LSP5503L datasheet PDF. This datasheet also covers the LSP5503L-LITE variant, as both devices belong to the same 3a 23v synchronous buck converter family and are provided as variant models within a single manufacturer datasheet.

Description

The LSP5503L is a monolithic synchronous buck regulator.

The device integrates 90 mΩ MOSFETS that provide 3A continuous load current over a wide operating input voltage of 4.5V to 23V.

Current mode control provides fast transient response and cycle-by-cycle current limit.

Features

  • Wide 4.5V to 23V Operating Input Range.
  • Fixed 340KHZ Frequency.
  • Integrated Power MOSFET Switches.
  • Output Adjustable from 0.925V to 0.8Vin.
  • Up to 93% Efficiency.
  • Programmable Soft-Start.
  • Stable with Low ESR Ceramic Output Capacitors.
  • Over Current Protection.
  • Short Circuit Protection.
  • Input Under Voltage Lockout.
  • Package： ESOP-8L.

LSP5503L 3A 23V Synchronous Buck Converter General Description The LSP5503L is a monolithic synchronous buck regulator. The device integrates 90 mΩ MOSFETS that provide 3A continuous load current over a wide operating input voltage of 4.5V to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn on. Features • 3A Output Current • Wide 4.5V to 23V Operating Input Range • Fixed 340KHZ Frequency • Integrated Power MOSFET Switches • Output Adjustable from 0.925V to 0.
