PIN FUNCTIONS
Pin #
Name Description
1, 8
NC
No Connect.
2
SW
Switch Output.
3
IN
Supply Voltage. The MP2371 operates from a +4.5V to +24V unregulated input. C1 is needed
to prevent large voltage spikes from appearing at the input.
4
EN
On/Off Control Input. Pull above 1.5V to turn the device on.
5
FB
Feedback. An external resistor divider from the output to GND, tapped to the FB pin sets the
output voltage. To prevent current limit run away during a short circuit fault condition the
frequency foldback comparator lowers the oscillator frequency when the FB voltage is below
250mV.
6
GND
Ground. This pin is the voltage reference for the regulated output voltage. For this reason care
must be taken in its layout. This node should be placed outside of the D1 to C1 ground path to
prevent switching current spikes from inducing voltage noise into the part.
7
BST
Bootstrap. This capacitor is needed to drive the power switch’s gate above the supply voltage. It
is connected between SW and BST pins to form a floating supply across the power switch
driver.
