Texas Instruments TLVM236x5 Buck Converter Power Module

Texas Instruments TLVM236x5 Synchronous Buck Converter Power Module is a 1.5A or 2.5A, 36V input DC/DC power module that combines flip chip on lead (FCOL) packaging, power MOSFETs, integrated inductor, and boot capacitor in a compact and easy-to-use 3.5mm × 4.5mm × 2mm, 11-pin QFN package. The small HotRod™ QFN package technology enhances the thermal performance, ensuring high ambient temperature operation. Devices with a resistor feedback divider can be configured for 1V up to 6V output.

The TLVM236x5 is designed to meet low standby power requirements for always-on industrial applications. The auto mode enables frequency to fold back when operating at light loads, allowing a no-load current consumption of 1.5µA at 13.5V VIN and high light load efficiency. A seamless transition between PWM and PFM modes and low MOSFET on resistances provides exceptional efficiency across the entire load range.

The Texas Instruments TLVM236x5 uses peak current mode architecture with internal compensation to maintain stable operation with minimal output capacitance. The RT pin can be used to set the frequency between 200kHz and 2.2MHz to avoid noise-sensitive frequency bands.
