LMR33640DDDAR TI Voltage Regulators - DC DC Switching Regulators
The LMR33640 is a 4-A synchronous step-down converter operating from a 3.8V to 36V input, with an adjustable output from 1V to 24V. It integrates high-side and low-side MOSFETs with a 400-kHz switching frequency, providing efficiency up to 95% at 12V to 5V conversion. The device includes integrated compensation, soft-start, and precision enable for programmable UVLO. Packaged in an 8-pin HSOIC (DDA) (4.9mm × 3.91mm) with PowerPAD, it is ideal for industrial and automotive 24-V/48-V battery systems. Applications include electric vehicle power distribution, industrial sensors, battery management systems, and automotive infotainment. In stock at HL Electronics – request a quote for fast delivery.
