Diodes Incorporated (Diodes Incorporated) having a current rise Release, buck and inverter functions - DC converter AL8812. The device integrates a 60V/3.6A NMOS channel to meet the basic functions of the DC-DC controller in a compact dual-band thermal pad DFN6040-12 package that reduces the form factor of the MR16 LED lamp circuit.
The ootprint of the AL8812 is 6mm x 4mm and the height of the board is only 0.6mm. The converter includes a temperature compensated reference, a comparator, a duty-controlled oscillator with an active current limit circuit, a driver, and a high current output switch.
The AL8812's input voltage range is 3V to 20V and the output voltage can be adjusted up to 60V. The new device operates over a wide supply voltage range and is suitable for medium voltage LEDs, 12VAC lighting applications and dimmable MR16 LEDs.
The converter typically has a shutdown current of less than 0.01μA and a maximum output switching current of 3.6A. It is equipped with an accurate reference of 2% tolerance and provides very precise voltage and current control.
Diodes combines the AL8812 with the constant current step-down converter AL8807A to provide a two-stage reference design for dimmable MR16 LEDs, providing good transformer compatibility and low current ripple at a very affordable bill of materials cost. wave.
