Product Introduction

UC3845AD8 PWM controller for current mode

illustrate

The control IC UC1842A/3A/4A/5A family is a pin-compatible series of improved versions of the UC3842/3/4/5 pins. Providing the necessary functions to control the current mode switching power supply, this home has the following improved features. The starting current is guaranteed to be less than 0.5 mA. The oscillator discharge is trimmed to 8.3 milliamps. In undervoltage lockout, the output stage can absorb less than the past of at least 10mA for a 1.2V 5V CC.
