Analog Devices MAX17548 | Demoboard MAX 17548EV KIT
42V, Dual-Output, Synchronous Step-Down Controller
Overview
| Topology | Buck Converter |
| Input voltage | 4.5-42 V |
| Output 1 | 5 V / 5 A |
| Output 2 | 3.3 V / 10 A |
Description
The MAX17548 EV kit provides a proven design to evalu¬ate the MAX17548 wide 4.5V to 42V input, dual-output, synchronous step-down DC-DC controller. The EV kit provides 5V/5A and 3.3V/10A at the outputs from a 6V to 42V input supply. The switching frequency of the EV kit is preset to 350kHz for optimal efficiency and component size. The EV kit features adjustable input undervoltage-lockout and soft-start time, selectable PWM/DCM modes, 180° out-of-phase/0° in-phase operation, current-limit threshold, and independent open-drain PGOOD signals.
