The TPSM365R6 or TPSM365R3 is a 600mA or 300mA, 65V input synchronous step-down DC/DC power module that combines 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 and low EMI. The device features the ultra-low operating IQ of 4µA at no load (24V to 3.3V VOUT). The TPSM365Rx is available in two fixed output voltage option supporting 3.3V and 5V, and an adjustable output voltage option supporting 1V to 13V range. The module only requires four external components for a 3.3V and 5V fixed output design The TPSM365Rx is optimized for excellent EMI performance and space constraint applications.

The TPSM365Rx uses a peak current mode control scheme with internal compensation to maintain stable operation with minimal output capacitance. The precision EN feature allows precise control of the device during start-up and shutdown. An open-drain PGOOD output provides a true indication of the output voltage status. The TPSM365Rx includes prebias start up, overcurrent, and temperature protections, making the TPSM365Rx an excellent device for powering a wide range of industrial applications. In the fixed option variants, the MODE/SYNC pin enables seamless transition from FPWM to PFM with a no-load standby quiescent current of less than 4µA, making sure of high efficiency and excellent transient response for the entire load-current range.
