Active Clamp Current Mode PWM Controller
LM5026
Active Clamp Current Mode PWM Controller
General DescriptionThe LM5026 PWM controller containsallof the features
necessaryto implement power converters utilizingthe active
clamp/ reset technique with current mode control. With the
active clamp technique, higher efficiencies and greater
power densities canbe realized comparedto conventional
catch windingor RDC clamp/ reset techniques. Two control
outputs are provided, the main power switch control
(OUT_A) andthe active clamp switch control (OUT_B). The
device canbe configuredto control eithera P-Channelor
N-Channel clamp switch. The main gate driver featuresa
compound configuration, consisting of both MOS
and Bipolar devices, providing superior gate drive character-
istics. The LM5026 canbe configuredto operate with bias
voltages overa wide input rangeof8Vto 100V. Additional
features include programmable maximum duty cycle, line
under-voltage lockout, cycle-by-cycle current limit, hiccup
mode fault operation with adjustable timeout delay, PWM
slope compensation, soft-start, 1MHz capable oscillator with
synchronization input/ output capability, precision reference
and thermal shutdown.
