GENERAL DESCRIPTION英语六级成绩多少分过
观点英语The ML4825 High Frequency PWM Controller is an IC controller optimized for u in Switch Mode Power Supply designs running at frequencies to 1MHz.
Propagation delays are minimal through the comparators and logic for reliable high frequency operation while slew rate and bandwidth are maximized on the error amplifier.This controller is designed to work in either voltage or current mode and provides for input voltage feed forward.A 1V threshold current limit comparator provides cycle-by-cycle current limit while exceeding a 1.4V threshold initiates a soft-start cycle. The soft start pin doubles as a maximum duty cycle clamp. An under-voltage lockout circuit with 800mV of hysteresis assures low startup current and drives the outputs low.
This controller is similar in architecture and performance to the UC1825 controller, however the ML4825 includes many features not found on the 1825. The features are t in Italics .
