Pin Functional Description

DRAIN (D) Pin:

Power MOSFET drain connection. Provides internal operating

current for both start-up and steady-state operation.

BYPASS (BP) Pin:

Connection point for a 0.1 µF external bypass capacitor for the

internally generated 5.8 V supply.

Y Package (TO-220-7B)

ENABLE/UNDER-VOLTAGE (EN/UV) Pin:

Thispinhasdualfunctions, enableinputandlineunder-voltage

sense. During normal operation, switching of the power

MOSFET is controlled by this pin. MOSFET switching is

terminated when a current greater than 50 µA is drawn out of

this pin. This pin also senses line under-voltage conditions

through an external resistor connected to the DC line voltage.

If there is no external resistor connected to this pin, TNY256

detects this and disables the line under-voltage function.
