Durel D356A
D356A is part of a family of highly integrated EL drivers based on Durel’s patented three-port (3P) topology, which offers built-in EMI shielding. This high efficiency device is well suited for backlighting most timepieces and liquid crystal displays for portable electronic applications. The D356A drives the EL lamp by repeatedly pumping charge through an external inductor with current from a DC source and discharging into the capacitance of the EL lamp load.| Part No. | D356A |
