ISL71043M, ISL71041M
Radiation Tolerant Single-Ended Current Mode PWM Controllers
The ISL71043M and ISL71041M are PWM controllers 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.
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.
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.
