UC3842AN Description


UC3842AN is a kind of SMPS controller manufactured by STMicroelectronics for OffLine and DC to DC converter applications. The internal circuits include UVLO, low start-up current circuit, temperature compensated reference, high gain error amplifier, current sensing comparator, and high current totem-pole output for driving a POWER MOSFET. UC3842AN applications include bipolar power transistor and field-effect transistor. More information can be found in the UC3842AN datasheet.



UC3842AN Features


  • Under-voltage lockout with hysteresis

  • Low start-up current below 0.3mA

  • Short shutdown delay time typ. 100ns

  • Cycle by cycle current limiting

  • Available in the 8-DIP and 8-SOP package



UC3842AN Applications


  • Bipolar power transistor

  • Field-effect transistor
