Connection and Application Information
12 Volt Input Dc to Ac Inverter
(1) Low ESR type input by-pass capacitor (22 uf - 100 uf) may be required to reduce reflected ripple.
(2) V
(3) Full brightness without PWM control requires that pin 3 be tied to Vin(+). Pin 3 must be at 0V to turn off.
(4) Duty Cycle 0% - 100%.
