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-Q200 qualified inductor and boot capacitor in a compact and easy-to-use package. The small HotRod QFN package enhances the thermal performance, making sure of 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 MODE/SYNC pin. The device only requires four external components for a 3.3V and 5V fixed output design which simplifies PCB layout and design.

The device is designed to meet low standby power requirements for always-on, automotive applications. Auto mode enables frequency foldback when operating at light loads allowing high light-load efficiency. DRSS is used to reduce the external components of the input EMI filter.
