Product details

Description

ORDERING INFORMATION The UC2825A-EP pulse width modulation (PWM) controller is an improved version of the standard UC2825. Performance enhancements have been made to several of the circuit blocks.Error amplifier gain bandwidth product is 12 MHz, while input offset voltage is 2 mV.Current-limit threshold is specified to a tolerance of 5%.Oscillator discharge current is specified at 10 mA for accurate dead-time control.Frequency accuracy is improved to 6%.Startup supply current, typically 100
