LMR23625CFPQDRRRQ1 PMIC Chip Step-Down Buck Switching Regulator 1V Output 2.5A

Description

The LMR23625CFPQDRRRQ1SIMPLE SWITCHER® is an easyto-use 36-V, 2.5-A synchronous step down regulator. With a wide input range from 4 V to 36 V, the device is suitable for various applications from industrial to automotive for power conditioning from unregulated sources. Peak-current-mode control is employed to achieve simple control-loop compensation and cycleby-cycle current limiting. A quiescent current of 75 μA makes it suitable for battery powered systems. Internal loop compensation means that the user is free from the tedious task of loop compensation design. This also minimizes the external components.

The LMR23625CFPQDRRRQ1 device has option for fixed-frequency, forcedpulse-width-modulation (FPWM) mode to achieve small output voltage ripple at light load. An extended family is available in 1-A (LMR23610-Q1), 1.5-A (LMR23615-Q1), and 3-A (LMR23630-Q1) load current options in pin-to-pin compatible packages, which allows simple, optimum PCB layout. A precision-enable input allows simplification of regulator control and system-power sequencing. Protection features include cycle-by-cycle current limit, hiccup-mode short-circuit protection and thermal shutdown due to excessive power dissipation.
