AV3843A - (AV3842A / AV3843A) LINEAR INTEGRATED CIRCUIT

Download the AV3843A datasheet PDF. This datasheet also covers the AV3842A variant, as both devices belong to the same (av3842a / av3843a) linear integrated circuit family and are provided as variant models within a single manufacturer datasheet.

General Description

The @vic AV3842A/3843A provide the necessary functions to implement off-line or DC to DC fixed frequency current mode , controlled switching circuits with a minimal external part count SOP-8

Key Features

  • Low external part count.
  • Low start up current ( Typical 0.12mA ).
  • Automatic feed forward compensation.
  • Pulse-by-Pulse current limiting.
  • Under-voltage lockout with hysteresis.
  • Double pulse Suppression.
  • High current totem pole output to drive MOSFET directly.
  • Internally trimmed band gap reference.
  • 500kHz operation DIP-8 BLOCK.
