Texas Instruments LMR38025QEVM Evaluation Module
Texas Instruments LMR38025QEVM Evaluation Module qualifies for the LMR38025-Q1 and the LMR38025 buck converters. This module uses an LMR38025SQDRRRQ1 synchronous buck converter with a wide duty-cycle range, spread spectrum, and cycle-by-cycle overcurrent protection. The LMR38025QEVM module operates at 80V maximum input voltage and delivers a 5V regulated output voltage at 400kHz switching frequency. This module features a 98% maximum duty cycle and PFM operation to improve efficiency at light load, and a programmable system under-voltage lockout through precision enable.
