DRAIN (D) Pin:
This pin is the power MOSFET drain connection. It provides
internal operating current for both startup and steady-state

2. It is a mode selector for the current limit value, depending on
the value of the capacitance added. Use of a 0.1 μ F
capacitor results in the standard current limit value. Use of a
1 μ F capacitor results in the current limit being reduced to

results in the current limit being increased to that of the next

3. It provides a shutdown function. When the current into the
bypass pin exceeds I SD , the device latches off until the
BP/M voltage drops below 4.9 V, during a power down. This
can be used to provide an output overvoltage function with a
Zener connected from the BP/M pin to a bias winding supply.

ENABLE/UNDERVOLTAGE (EN/UV) Pin:
This pin has dual functions: enable input and line undervoltage
sense. During normal operation, switching of the power
MOSFET is controlled by this pin. MOSFET switching is
terminated when a current greater than a threshold current is
drawn from this pin. Switching resumes when the current being
