ISL71043M, ISL71041M

Radiation Tolerant Single-Ended Current Mode PWM Controllers

The ISL71043M and ISL71041M are PWM controllers

Features

▪ 1A MOSFET gate driver

suitable for a wide range of power conversion

applications including boost, flyback, and isolated

output configurations. Fast signal propagation and

output switching characteristics make these ideal

products for existing and new designs.

▪ 90µA typical start-up current, 125µA maximum

▪ 35ns propagation delay current sense to output

▪ Fast transient response with Peak Current mode

control

Features include up to 13.2V operation, 2.9mA

operating current, 90µA typical start-up current,

adjustable operating frequency to 1MHz and, 1A

current drive capability with 35ns rise and 29ns fall

times.

▪ 9V to 13.2V operation

▪ Adjustable switching frequency to 1MHz

▪ 35ns rise time and 29ns fall time with 1nF output

load

The ISL71041M and ISL71043M are available in an

8 LD TDFN package and the ISL71043M is also

available in an 8 LD SOIC package. Both packages

are specified across the extended temperature range

of -55°C to +125°C.

▪ Trimmed timing capacitor discharge current for

accurate dead time/maximum duty cycle control

▪ 1.5MHz bandwidth error amplifier

▪ Tight tolerance voltage reference over line, load,

and temperature

▪ ±3% current limit threshold

Applications

▪ Ni/Pd/Au-Ag lead finish (Tin (Sn) free)

▪ Characterized radiation levels - ISL71041M

• Low Dose Rate (LDR) (0.01rad(Si)/s): 30krad(Si)

▪ Radiation acceptance testing - ISL71043M

• Low Dose Rate (LDR) (0.01rad(Si)/s): 50krad(Si)

▪ Current mode switching power supplies

▪ Isolated buck and flyback regulators

▪ Boost regulators

▪ Direction and speed control in motors

▪ Control of high current FET drivers

▪ Single event burnout LET 43MeV•cm /mg
