Isolated Motor Drive Gate Power Supply

TDFN-EP

3mm x 3mm

*EP = Exposed Pad. Connect to ground.

The MAX22256/MAX22258 family provides a simple

solution for making isolated power supplies over

15W. These devices drive a transformer’s primary

coil with up to 650mA

of current from a wide 5V

RMS

to 36V DC supply. The MAX22256B/C are optimized

for LLC-type resonant topology, improving efficiency,

and reducing switching noise.

A FAULT output alerts the main controller during an

over-temperature or over-current condition. These

devices feature a low-power mode to reduce the overall

supply current to 0.7mA (typ) when the driver is not in

use.

•

Isolated +24V PLC Field Supply

The MAX22256/MAX22258 family features

resistor-adjustable current limit that allows indirect

limiting of the secondary-side load current and

protects the primary power source in the event of

secondary- or field-side failure.

The device can be operated using the accurate internal

oscillator or driven by an external clock to synchronize

multiple devices and precisely set the switching

frequency.
