The UC3842AN is a current-mode Pulse Width Modulation (PWM) controller IC from Motorola Semiconductor, optimized for off-line and DC-to-DC converter applications requiring minimal external components. This device features a fixed frequency operation up to 500 kHz and supports a wide supply voltage range from 16V to 28V, with a maximum duty cycle of 100%.
Key electrical characteristics include a low start-up current of less than 1 mA, automatic feedforward compensation, and pulse-by-pulse current limiting. It also incorporates undervoltage lockout with hysteresis, double-pulse suppression, and a high-current totem-pole output. The internal oscillator can be set using external resistor and capacitor components connected to the RT/CT pin.
Designed for versatility, the UC3842AN supports multiple topologies including Boost, Buck, Buck-Boost, Flyback, and Forward converters. It is housed in an 8-PDIP package, suitable for through-hole mounting. The operating temperature range is from 0 to 70 degrees Celsius.
