Image of Texas Instruments' TPSM365R6 Synchronous Buck Converter Power Module Texas Instruments' TPSM365R6 is a 600 mA 65 V input synchronous step-down DC/DC power module that combines power MOSFETs, an integrated inductor, and a boot capacitor in a compact and easy-to-use 3.5 mm x 4.5 mm x 2 mm 11-pin QFN package. The small HotRod™ QFN package technology enhances the thermal performance and low EMI. The device features an ultra-low operating I_Q of 4 μA at no load (24 V_IN to 3.3 V_OUT).

The TPSM365R6 is available in two fixed output voltage options of 3.3 V and 5 V and an adjustable output voltage range of 1 V to 13 V. The module requires four external components for a fixed output solution of 3.3 V and 5 V. The TPSM365R6 is optimized for excellent EMI performance and space-constrained applications.
