The ISL884xAMBEP is a high-performance Enhanced Product (EP) single-ended current mode PWM controller, suitable for a wide range of power conversion applications including flyback, forward, and boost output configurations. It offers fast signal propagation and output switching characteristics, making it ideal for both existing and new designs. Key features include 30V operation, low operating current, 90µA start-up current, adjustable operating frequency up to 2MHz, and high peak current drive capability with 20ns rise and fall times.
The ISL8840AMBEP is a high‑performance, drop‑in replacement for legacy 28C4x and 18C4x PWM controllers. It is suited for flyback, forward and boost power‑conversion topologies and offers fast signal propagation and output switching.
Key features include 30 V operation, low 125 µA start‑up current, adjustable frequency up to 2 MHz, 20 ns rise/fall times, 35 ns propagation delay, and a 1.5 MHz bandwidth error amplifier. The device is supplied in an 8‑lead narrow‑body SOIC package and is covered by full Mil‑Temp performance from –55 °C to +125 °C.
