NCP1395A/B

High Performance Resonant

Mode Controller

The NCP1395A/B offers everything needed to build a reliable and

rugged resonant mode power supply. Its unique architecture includes

a 1.0 MHz Voltage Controller Oscillator whose control mode brings

flexibility when an ORing function is a necessity, e.g. in multiple

feedback paths implementations. Protections featuring various

reaction times, e.g. immediate shutdown or timer−based event,

brown−out, broken optocoupler detection etc., contribute to a safer

converter design, without engendering additional circuitry

complexity. An adjustable deadtime also helps lowering the

shoot−through current contribution as the switching frequency

increases.

Finally, an onboard operational transconductance amplifier allows

for various configurations, including constant output current working

mode or traditional voltage regulation.

Features

• High Frequency Operation from 50 kHz up to 1.0 MHz

• Selectable Minimum Switching Frequency with "3% Accuracy

• Adjustable Deadtime from 150 ns to 1.0 ms

• Startup Sequence via an Adjustable Soft−Start

• Brown−Out Protection for a Simpler PFC Association

• Latched Input for Severe Fault Conditions, e.g. Overtemperature

or OVP
