Product details

What this Himalaya buck does on your rail

The MAX15462CATA+T is a step-down (buck) switching regulator from Maxim Integrated's Himalaya series, delivering up to 300 mA from a 4.5 V to 42 V input rail. Switching frequency is fixed at 500 kHz, which keeps the inductor small while staying below the AM band. The part comes in an 8-TDFN (2x2 mm) package, surface-mount, and is ROHS3 compliant.

300 mA output — sizing the load budget

300 mA is the continuous output rating. That covers a sensor module, a small microcontroller plus its peripherals, or an isolated bias supply.

Synchronous rectification — efficiency without the diode

The built-in synchronous rectifier replaces the usual Schottky catch diode. That eliminates the diode's forward voltage drop and its reverse-recovery losses, which matters at 500 kHz switching.

ROHS3 compliant.

Frequently asked questions

Is MAX15462CATA+T synchronous or asynchronous?

It is a synchronous rectifier design — the internal low-side FET replaces the external catch diode.

Can the MAX15462CATA+T replace the MAX15462CATA?

The MAX15462CATA+T is the Tape & Reel variant of the base MAX15462CATA. The electrical specifications are identical; the only difference is the packaging format (Tape & Reel vs. possibly tube or tray). Check the reel quantity and your pick-and-place setup, but the silicon is the same.
