EVAL_TDA38740_3.3VOUT

概要

Evaluation demoboard 3.3 Vout for IPOL single-voltage regulator TDA38740

The EVAL_TDA38740_3.3VOUT enables full configuration of OptiMOS™ IPOL single-voltage synchronous buck regulator TDA38740 IC using the PMBus and/or using pin-strapped resistors. A USB dongle is used to establish communication between the IC and the PC via the 3-pin on-board header.

Infineon's XDP™ Designer GUI is used to interface and program the TDA38740 IC.

特長

  • Optional forced continuous conduction mode and diode emulation for enhanced light load efficiency
  • Programmable switching frequency from 400 kHz-2 MHz in steps of 200 kHz, excluding 1600 kHz
  • Monotonic start-up with selectable soft-start time through PMBus and enhanced pre-bias start-up
  • Thermally compensated internal over-current protection with eight unique selectable settings
  • Enable input with voltage monitoring capability and power good output

利点

  • 24 writes to MTP
  • Small size with 5x6 mm2 PQFN
  • PMBus communication
