Part Details:

19-0784; Rev 1; 7/07 EVALUATION KIT AVAILABLE 1.5MHz Dual Step-Down DC-DC Converters with Dual LDOs and Individual Enables MAX8667/MAX8668 General Description Features The MAX8667/MAX8668 dual step-down converters o Tiny, Thin QFN 3mm x 3mm Package with dual low-dropout (LDO) linear regulators are o Individual Enables intended to power low-voltage microprocessors or o Step-Down Converters DSPs in portable devices. They feature high efficiency 600mA Guaranteed Output Current on OUT1 with small external component size. The step-down 1200mA Guaranteed Output Current on OUT2 converters are adjustable from 0.6V to 3.3V (MAX8668) Tiny Size 2.2µH Chip Inductor (0805) or factory preset (MAX8667) with guaranteed output Output Voltage from 0.6V to 3.3V (MAX8668) current of 600mA for OUT1 and 1200mA for OUT2. The Ultra-Fast Line and Load Transients 1.5MHz hysteretic-PWM control scheme allows for tiny Low 25µA Supply Current Each external components and reduces no-load operating o LDOs current to 100µA with all outputs enabled. Dual low-qui- 300mA Guaranteed escent-current, low-noise LDOs operate down to 1.7V Low 1.7V Minimum Supply Voltage supply voltage. The MAX8667/MAX8668 have individ- Low Output Noise ual enables for each output, maximizing flexibility. The MAX8667/MAX8668 are available in the space- Ordering Information saving, 3mm x 3mm, 16-pin thin QFN package.
