Product details

Description

Pin Pin (SOT 223) (PDIP 8) Function 1 1 VCC 2 2 Control Input 4 3, 7, 8 Ground 4 No Connection 3 5 Power Switch Drain Description This is the positive supply voltage input.During startup, power is supplied to this input from Pin 5. When VCC reaches VCC(on), the Startup Circuit turns off and the output is allowed to begin switching with 1.0 V hysteresis on the VCC pin.The capacitance connected to this pin programs fault timing and frequency modulat

Features

an active startup regulator circuit that eliminates the need for an auxiliary bias winding on the converter transformer, fault detector and a programmable timer for converter overload protection, unique gated oscillator configuration for extremely fast loop response with double pulse suppression, power switch current limiting, input undervoltage lockout with hysteresis, thermal shutdown, and auto restart fault detection. These devices are available in economical 8.
