High Performance Resonant

Mode Controller with

Integrated High-Voltage

Drivers

www.onsemi.com

The NCP1397 is a high performance controller that can be utilized

in half bridge resonant topologies such as series resonant, parallel

resonant and LLC resonant converters. It integrates 600 V gate

drivers, simplifying layout and reducing external component count.

With its unique architecture, including a 500 kHz Voltage Controlled

Oscillator whose control mode permits flexibility when an ORing

function is required, the NCP1397 delivers everything needed to build

a reliable and rugged resonant mode power supply.

CASE 751AM

The NCP1397 provides a suite of protection features with

configurable settings to optimize any application. These include:

auto−recovery or fault latch−off, brown−out, open optocoupler,

soft−start and short−circuit protection. Deadtime is also adjustable to

overcome shoot through current.
