MIC2842A規(guī)格書詳情
General Description
The MIC2842A is a high efficiency White LED (WLED) driver designed to drive up to four LEDs and greatly extend battery life for portable display backlighting, and keypad backlighting in mobile devices. The MIC2842A architecture provides the highest possible efficiency by eliminating switching losses present in traditional charge pumps or inductive boost circuits. With a typical dropout of 40mV at 20mA, the MIC2842A allows the LEDs to be driven directly from the battery eliminating switching noise and losses present with the use of boost circuitry.
Features
? High Efficiency (no Voltage Boost losses)
? Dynamic Average Matching? (DAM?)
? Single wire digital control
? Input voltage range: 3.0V to 5.5V
? Dropout of 40mV at 20mA
? Matching better than ±1.5 (typical)
? Current accuracy better than ±1.5 (typical)
? Maintains proper regulation regardless of how many
channels are utilized
? Available in a 10-pin 2mm x 2mm Thin MLF? package
Applications
? Mobile handsets
? Handset LCD backlighting
? Handset keypad backlighting
? Camera flash (see MIC2843A datasheet)
? Digital cameras
? Portable media/MP3 players
? Portable navigation devices (GPS)
? Portable application
