uc2842/3/4/5 uc3842/3/4/5 october 1998 currentmode pwm controller. optimized for off-line and dc to dc. converters. lowstart-up current (< 1 ma) automatic feed forward compensa- 3 UC19432 UC29432 UC39432 UC39432B COLL: The collector of the output transistor with a maxi- mum voltage of 36V. This pin is the output of the transconductance amplifier. The overall open loop volt- during IC operating. At no load or light load condition, most of the power dissipation in a switching mode power supply is from switching loss on the MOSFET transistor, the core loss of the transformer and the loss on the snubber circuit. UC3524AN ti UC3524A, Advanced Regulating Pulse Width Modulators . FEATURES. DESCRIPTION. The UC1524A family of regulating PWM ICs has been designed to retain the same highly versatile architecture of the industry standard UC1524 (SG1524) while offering substantial improvements to many of its limitations. uc2842b/3b/4b/5b uc3842b/3b/4b/5b march 1999 high performance current mode pwm controller. trimmed oscillator for precise fre-. quency control oscillator frequency guaranteed The content and copyrights of the attached material are the property of its owner.
