Applications
TPS40170MRGYTEP targets high-voltage DC-DC step-down power supplies in industrial automation, 48 V telecom equipment, and automotive body electronics where the input bus ranges from 4.5 V to 60 V. Its synchronous buck topology supports external N-channel MOSFETs for high-current multi-ampere outputs, enabling designs for motor-driver pre-regulators and point-of-load converters on 48 V battery systems. The enhanced plastic (EP) qualification makes it suitable for under-hood automotive applications with wide ambient temperature ranges.

Frequently Asked Questions
What input voltage range does TPS40170MRGYTEP support, and which industrial bus standards does this cover?
TPS40170MRGYTEP supports a 4.5 V to 60 V input range. This covers the three most common industrial power bus standards: the 12 V low-voltage bus, the 24 V standard industrial bus, and the 48 V high-efficiency bus used in telecom and automotive 48 V mild-hybrid systems, allowing a single controller design to address all three standards without hardware changes.
For a 48 V to 5 V industrial point-of-load converter, which control method does TPS40170MRGYTEP use and how does it simplify design?
TPS40170MRGYTEP uses voltage-mode pulse-width modulation (PWM) control. Voltage-mode PWM simplifies compensation network design by allowing a single Type III RC network around the error amplifier to stabilize the control loop, avoiding the current-sense resistor and slope compensation circuitry required for current-mode controllers, which reduces component count by 3 to 5 passives per converter stage.
How many external MOSFETs does TPS40170MRGYTEP require, and what output current levels can it support with standard discrete FETs?
TPS40170MRGYTEP requires 2 external N-channel MOSFETs — one high-side and one low-side — for synchronous buck operation. Using 60 V N-channel MOSFETs with 5 mΩ to 10 mΩ on-resistance, designers can build converters delivering 10 A to 20 A output current, enabling point-of-load designs that supply entire digital processor subsystems from a single 48 V bus input.
