MAX8822ETE+規(guī)格書詳情
General Description
The MAX8822 drives up to four white light-emitting diodes (LEDs) with regulated constant current for display backlighting in cell phones, digital cameras, PDAs, and other handheld devices. By utilizing a proprietary negative 0.5x inverting charge pump and innovative independent low-dropout (LDO) adaptive current regulators, very high efficiency is achieved over the full 1-cell Li+ battery voltage range, even with large LED VF mismatch. The 1MHz fixed-frequency switching allows for tiny external components. The regulation scheme is optimized to ensure low EMI and low input ripple. Two 200mA, low-noise, high power-supply-rejection-ratio (PSRR) LDOs with programmable output voltages are included on-chip to provide power to camera modules or other devices.
Features
? High-Efficiency Charge Pump for Up to Four White LEDs
??? Independent Adaptive Voltage Supply for Each LED

??? 16 Different Output Voltage Combinations Up to 3.3V
??? High 60dB PSRR at 10kHz
? Flexible Single-Wire Control for Dimming and LDO Output Voltage
? Low 0.5μA (typ) Shutdown Mode
? Soft-Start Limits Inrush Current
? Thermal Shutdown and Open- and Short-Circuit Protection
? Tiny 16-Pin, 3mm x 3mm Thin QFN Package
??? (0.8mm max Height) with Exposed Paddle
Applications
??? White LED Backlighting
??? Cell Phones and Smartphones
