Product Overview

L5973D013TR is a 2.5A switch step-down switching regulator. The L5973D is a step-down monolithic power switching regulator with a minimum switch current limit of 2.5A so it is able to deliver more than 2A DC current to the load depending on the application conditions. The device uses an internal P-channel D-MOS transistor (with a typical Rdson of 250mohm) as switching elements to minimize the size of the external components. Pulse-by-pulse current limit with the internal frequency modulation offers an effective constant current short circuit protection. Typical applications are consumer: STB, DVD, TV, VCR, car radio, LCD monitors, networking: XDSL, modems, DC-DC modules, computer: printers, audio/graphic cards, optical storage, hard disk drive, industrial: changers, car battery, DC-DC converters.
  • 2.5A internal switch, operating input voltage from 4V to 36V
  • Protection against feedback disconnection
  • Output voltage adjustable from 1.235V to 35V, 3.3V / (±2%) reference voltage
  • Low dropout operation: 100% duty cycle
  • 250KHz internally fixed frequency
  • Voltage feedforward, zero load current operation
  • Internal current limiting, inhibit for zero current consumption
  • Synchronization, thermal shutdown
  • HSOP8 (exposed pad) package
  • Operating junction temperature range from -40 to 150°C
