Applications
The TPSDC63802DLAR is designed for dual-rail point-of-load power conversion in industrial control boards, automotive infotainment modules, and telecommunications equipment powered from 12 V to 36 V bus voltages. Its dual independent buck channels can supply two different regulated voltages simultaneously, such as 3.3 V and 5 V, from a single IC, reducing total solution size and BOM cost. The 38 V input tolerance makes it suitable for 24 V industrial supplies with transient overvoltage headroom.

Frequently Asked Questions
What is the maximum input voltage for the TPSDC63802DLAR, and how much headroom does it provide above a 24 V industrial supply?
The TPSDC63802DLAR supports a maximum input voltage of 38 V, providing 14 V of headroom above a nominal 24 V industrial supply rail. This margin accommodates load-dump transients and supply fluctuations common in 24 V factory automation and motor drive environments without triggering overvoltage protection, ensuring reliable continuous operation.
Can the TPSDC63802DLAR supply two independent output voltages simultaneously, and what is the per-channel current limit?
Yes, the TPSDC63802DLAR is a dual-channel device that can generate 2 independent regulated output voltages simultaneously, each at up to 2 A continuous output current. This enables a single IC to power both a 3.3 V digital logic rail and a 5 V analog supply rail in a mixed-signal system, reducing the number of power converter ICs and simplifying thermal management on the PCB.
How does the TPSDC63802DLAR's integrated switch topology compare to discrete buck designs for tight board space budgets?
The TPSDC63802DLAR integrates both high-side and low-side power MOSFETs internally, eliminating 4 discrete switch components per channel compared to external-FET buck controllers. This integration reduces PCB footprint by typically 30% to 50% compared to a discrete 2 A synchronous buck circuit, lowers parasitic inductance in the switching loop, and simplifies EMI layout by shortening the high-frequency current loop to within the DLA package.
