Improved Industry Standard Single-Ended
Current Mode PWM Controller
The ISL6840, ISL6841, ISL6842, ISL6843, ISL6844,
ISL6845 family of adjustable frequency, low power, pulse
width modulating (PWM) current mode controllers is
designed for a wide range of power conversion applications
including boost, flyback, and isolated output configurations.
Peak current mode control effectively handles power
transients and provides inherent overcurrent protection.
This advanced BiCMOS design is pin compatible with the
industry standard 384x family of controllers and offers
significantly improved performance. Features include low
operating current, 60
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
60
μ
A startup current, 100
μ
A maximum
25ns propagation delay current sense to output
Fast transient response with peak current mode control
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
High bandwidth error amplifier
Tight tolerance voltage reference over line, load, and
temperature
Tight tolerance current limit threshold
Pb-Free Plus Anneal Available (RoHS Compliant)
