PIN FUNCTIONS
Pin #
Name Description
1
SW
Power Switch Output. SW is the drain of the internal MOSFET switch. Connect the
power inductor and output rectifier to SW. SW can swing between GND and 25V.
2
GND Ground
3
FB
Feedback Input. The MP1523 regulates the voltage across the current sense
resistor between FB and GND. Connect a current sense resistor from the bottom of
the LED string to GND. Connect the bottom of the LED string to FB. The regulation
threshold is 0.4V.
4
EN
Regulator On/Off Control Input. A high input at EN turns on the converter, and a low
input turns it off. When not used, connect EN to the input source for automatic
startup. If EN is driven over 6V, place a resistor in series with EN to limit current to
10μA or less.
Do not leave EN floating!
5
BIAS Internal Power Input. BIAS powers the internal circuitry and measures the output
voltage for open circuit protection. Connect BIAS to the output at the top of the LED
string to enable open load shutdown feature (see Figure 3). Connect BIAS to the
input to eliminate open load shutdown feature (see Figure 2).
