2.3.5 TPSM33620-Q1

The TPSM336xx-Q1 is a 0.6A, 1A, or 2A, 36V input, automotive, synchronous step-down DC/DC power module that combines flip-chip on lead packaging, integrated power MOSFETs, AEC-Q100 qualified inductor and boot capacitor in a compact and easy-to-use package. The small HotRod QFN package enhances the thermal performance, enabling high ambient temperature operation. The spread spectrum helps achieve excellent EMI performance. The device is available in two fixed output voltage options supporting 3.3V and 5V. The devices can be configured for 1V up to 7V output with a feedback divider and operated in auto or forced PWM mode through the MODE/SYNC pin. The device only requires four external components for a 3.3V and 5V fixed output design simplifying PCB layout and design.
