Technical Details & Description

Dual-output automotive buck for ECU rails

The MAX20019ATBA/V+T is a dual-channel step-down (buck) switching regulator. It delivers two fixed output voltages — 3.3 V on one channel and 1.8 V on the other — each rated for 500 mA continuous output current. The part operates from a 3.5 V to 17 V input bus.

Switching frequency and external component sizing

The 3.2 MHz switching frequency is fixed; there is no SYNC pin for external clock synchronisation. The part does not include internal synchronous rectification — an external Schottky diode per channel is required in the BOM.

Frequently asked questions

Does MAX20019ATBA/V+T have synchronous rectification?

No. Synchronous rectification is not implemented, so an external Schottky diode is required per output channel for the low-side rectifier function.

What is the output current of MAX20019ATBA/V+T?

Each of the two outputs is rated for 500 mA continuous current, providing a combined 1 A total output capability from the dual channels.
