Features

Description

The IR2086S(PbF) is a self oscillating full-bridge controller and driver IC

with 50% duty cycle ideally suited for 36V-75V full-bridge DC Bus

Converters.

Dead time can be controlled through proper selection of C

from 50 to 200nsec. Internal soft start increases pulse width on power up

and maintains equal pulse widths for the high and low outputs throughout

the start up cycle. Undervoltage lockout prevents operation if Vcc is less than

7.5 Vdc. Over current shutdown occurs when the voltage on the Cs pin

exceeds 200mV. Restart after overcurrent trip can be delayed by adjusting

the external capacitor. The delay time ranges from 10 s to 1s.

Notes and DesignTips

for proper circuit board

layout.

Simple primary side control solution to enable full-bridge

DC-Bus Converters for 48V distributed systems with reduced

component count and board space.

Frequency and dead time set by two external components

Maximum 500KHz per channel output with 50% duty cycle

Adjustable dead time 50nsec ~ 200nsec

Floating channel designed for bootstrap operation up to +100Vdc

High and low side pulse width matching to +/- 25nsec

Overcurrent protection with adjustable hiccup period.

Undervoltage lockout and internal soft start
