FN9238.0

Industry Standard Single-Ended Current

Mode PWM Controller

Features

• 1A MOSFET gate driver

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.

• 90µA start-up current, 125µA 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

Features include 30V operation, low operating current, 90µA

start-up current, adjustable operating frequency to 2MHz,

and high peak current drive capability with 20ns rise and fall

times.

• Trimmed timing capacitor discharge current for accurate

deadtime/maximum duty cycle control

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
