Pin Descriptions
VPWR
VPWR is the power connection for the IC. UVLO
enables/disables the output and places the device into a
standby mode even if AUXIN is externally biased.
To optimize noise immunity, bypass VPWR to GND with a
ceramic capacitor as close to the VPWR and GND pins as
possible.
AUXIN
This is the input for an external bias source typically provided
by an auxiliary transformer winding. This input is not required
and may be grounded or left open. Maximum input bias is 40V.
ENABLE
The positive logic on/off control input. A logic high enables
VSW. Asserting this signal low turns off VSW. ENABLE and
ENABLE_N are logically ORed. Either signal can enable VSW,
but both must be false to disable VSW.
ENABLE_N
The negative logic on/off control input. A logic low enables
VSW. Asserting this signal high turns off VSW. ENABLE and
ENABLE_N are logically ORed. Either signal can enable VSW,
but both must be false to disable VSW.
GND
Signal and power ground connections for this device.
VSW
This is the switched regulated low voltage output supply that is
derived from VPWR or AUXIN. Its output is adjustable from
1.5V to 20V using an appropriate divider from VSW to VSW_FB.
Protection circuitry prevents the output from exceeding 25V in
the event of a fault on VSW_FB (short high or low). The
minimum output current capability is 100mA. VSW requires a
minimum load of 3mA.
VSW_FB
The feedback pin for VSW. A divider from VSW to ground sets
feedback for VSW and determines the output voltage.
