Data Sheet
January 3, 2006
FN9238.1
Industry Standard Single-Ended Current
Mode PWM Controller
The ISL8843 is an industry standard drop-in replacement for
the popular 28C43 and 18C43 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
