The UC3842A is a fixed PWM controller designed for Off-Line and DC to DC converter applications. Manufactured by Linx Technologies Inc., this component is suitable for various power management needs.
Key electrical specifications include a maximum supply voltage of 30V and a maximum output current of 1A. The device operates at frequencies up to 500kHz, with a typical start current of 0.2mA and a short shutdown delay time of 100ns. It features under-voltage lockout (UVLO) thresholds of 16V (on) and 10V (off), and an output swing limiting of 22V.
The UC3842A is housed in a SOIC package, making it suitable for surface mount applications. Its operating temperature range is from 0°C to 70°C.
This controller integrates essential circuits such as UVLO, a low start-up current circuit, a temperature-compensated reference, a high-gain error amplifier, a current sensing comparator, and a high-current totem-pole output for driving a power MOSFET.
The maximum supply voltage is 30V.
The maximum output current is 1A.
The operating temperature range is 0°C to 70°C.
The UC3842A is available in an SOIC package.
The maximum operating frequency is 500kHz.
The typical reference output voltage is 5V at 25°C with 1mA load.
The UVLO turn-on threshold is 16V and the turn-off threshold is 10V.
