The AAT15061 is a boost DC-DC converter for white LED applications. This powerful device is equipped with an internal MOSFET capable of supporting up to 13 3.2V/20mA LEDs. Additionally, the current-setting resistor between the FB pin and GND pin maintains consistent LED currents essential for uniform brightness.
With a fixed high operation frequency of 1.4MHz, the device design allows the use of smaller external components and saves PCB size. The AAT15061 also features an internal soft-start mechanism to effectively reduce inrush current, and a fool-proof 44V OVP protection function to prevent misuse. The AAT15061 is available in space-saving TSOT23-6 (TSOT26) and SOT23-6 (SOT26) packages ideal for the portable backlighting applications.
