3842B / 3843B
LINEAR INTEGRATED CIRCUIT
QW-R103-012,A
HIGH PERFORMANCE CURRENT
MODE CONTROLLERS
DESCRIPTION
Th

AV
3842B/3843B are specifically designed for
Off-Line and dc-to-dc converter applications offering the
designer a cost-effective solution with minimal external
components.
The
AV
3842B has UVLO thresholds 16V (on) and 10V(off),
ideally suited for off-line converters. The
AV
3843B is tailored
for lower voltage applications having UVLO thresholds of
8.5V(on) and 7.6V(off).
FEATURES
*Trimmed Oscillator for Precise Frequency Control
*Oscillator Frequency Guaranteed at 250kHz
*Current Mode Operation to 500kHz
*Automatic Feed Forward Compensation
*Latching PWM for Cycle-By-Cycle Current Limiting
*Internally Trimmed Reference with Undervoltage Lockout
*High Current Totem Pole Output
*Undervoltage Lockout with Hysteresis
*Low Startup and Operating Current
