+2.7V, Low-Power, 2-Channel, 108ksps, Serial 10-Bit ADCs in 8-Pin MAX
General Description
The MAX157, MAX159 low-power, 10-bit analog-to-digital converters (ADCs) are available in 8-pin MAX and DIP packages. Both devices operate with a single +2.7V to +5.25V supply and feature a 7.4 s successive-approximation ADC, automatic power-down, fast wake-up (2.5 s), an on-chip clock, and a high-speed, 3-wire serial interface. Power consumption is only 3.2mW (VDD = +3.6V) at the

White LED Current Regulator with 1x/1.5x High-Efficiency Charge Pump - LED
19-2526; Rev 0; 7, 02
White LED Current Regulator with 1x, 1.5x High-Efficiency Charge Pump
General Description
The MAX1570 fractional charge pump drives up to five white LEDs with regulated constant current for uniform intensity. The MAX1570 maintains the highest possible efficiency over the full 1-cell lithium-ion (Li+) battery input voltage range by utilizing a 1x, 1.5x fractional charge pump and very-low-dropout current regulators. The MAX1570 operates with 1MH- fixed-frequency switching,
