The TPSM365R6 or TPSM365R3 is a 600-mA or 300-mA, 65-V input synchronous step-down DC/DC power module that combines power MOSFETs, integrated inductor and boot capacitor in a compact and easy-to-use 3.5-mm × 4.5-mm × 2-mm, 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 4 µA at no load (24 V to 3.3-V VOUT). The TPSM365Rx is available in two fixed output voltage option supporting 3.3 V and 5 V, and an adjustable output voltage option supporting 1-V to 13-V range. The module only requires four external components for a 3.3-V and 5-V fixed output solution. 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 4 µA, ensuring high efficiency and superior transient response for the entire load-current range.
