Product Introduction
The TPSM336x5 is a 1.5-A or 2.5-A, 36-V input synchronous step-down DC/DC power module that combines flip chip on lead (FCOL) packaging, 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, ensuring high ambient temperature operation. In addition, in conjuction with spread spectrum, the device provides excellent EMI performance. Devices can be configured for 1-V up to 15-V output with a feedback divider and operated.
The TPSM336x5 is specifically designed to meet low standby power requirements for always on, industrial applications. Auto mode enables frequency foldback when operating at light loads, allowing a no load current consumption of 1.5 μA at 13.5 VIN and high light load efficiency. A seamless transition between PWM and PFM modes along with low MOSFET ON resistances provide exceptional efficiency across the entire load range.
The TPSM336x5 uses peak current mode architecture with internal compensation to maintain stable operation with minimal output capacitance. DRSS is used to reduce the external components of the input EMI filter. The RT pin variant can be used to synchronize or set the frequency between 200 kHz and 2.2 MHz to avoid noise sensitive frequency bands.
