1. Specifications
1.1 Package Pinout
1.3 Absolute Maximum Ratings
Electrical absolute maximum ratings are at 25°C.
Absolute maximum ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at conditions
beyond those indicated in the operational sections of this
data sheet is not implied.

Input voltage
LED Current Sense input. Internal current
sense threshold is set at 250mV. The external
sense resistor sets the maximum LED current.
Device Ground
External MOSFET gate driver output
Low-frequency PWM dimming control input with
internal pull-down resistor.
Regulated supply voltage output. Requires a
storage capacitor to GND. Can be overdriven by
external voltage applied to V
Linear Dimming. Apply a voltage less than
V
Resistor to GND sets the oscillator/primary
PWM frequency.
Electrical and thermal conductive pad on the
bottom of the MXHV9910BE. Connect this pad
to ground, and provide sufficient thermal
coupling to remove heat from the package.
