High Performance Industry Standard
Single-Ended Current Mode PWM
Controller
The ISL884xA is a high performance drop-in replacement for
the popular 28C4x and 18C4x PWM controllers suitable for a
wide range of power conversion applications including
boost, flyback, and isolated output configurations. Its fast
signal propagation and output switching characteristics
make this an ideal product for existing and new designs.
Features include 30V operation, low operating current, 90 μ A
start-up current, adjustable operating frequency to 2MHz,
and high peak current drive capability with 20ns rise and fall
times.
Features
? 1A MOSFET gate driver
? 90 μ A start-up current, 125 μ A maximum
? 35ns propagation delay current sense to output
? Fast transient response with peak current mode control
? 30V operation
? Adjustable switching frequency to 2MHz
? 20ns rise and fall times with 1nF output load
? Trimmed timing capacitor discharge current for accurate
deadtime/maximum duty cycle control
? 1.5MHz bandwidth error amplifier
