Features and Benefits
- 94% Efficient at 200mA Output Current
- 16µA Quiescent Supply Current
- Internal Synchronous Rectifier (no external diode)
- 0.1µA Logic-Controlled Shutdown
- LBI/LBO Low-Battery Detector
- Selectable Current Limit for Reduced Ripple
- Low-Noise, Anti-Ringing Feature (MAX1676)
- 8-Pin and 10-Pin µMAX Packages
- Preassembled Evaluation Kit (MAX1676EVKIT)
The MAX1674/MAX1675/MAX1676 compact, high-efficiency, step-up DC-DC converters fit in small µMAX packages. They feature a built-in synchronous rectifier, which improves efficiency and reduces size and cost by eliminating the need for an external Schottky diode. Quiescent supply current is only 16µA.
The input voltage ranges from 0.7V to VOUT, where VOUT can be set from 2V to 5.5V. Start-up is guaranteed from 1.1V inputs. The MAX1674/MAX1675/MAX1676 have a preset, pin-selectable output for 5V or 3.3V. The outputs can also be adjusted to other voltages using two external resistors.
All three devices have a 0.3Ω N-channel MOSFET power switch. The MAX1674 has a 1A current limit. The MAX1675 has a 0.5A current limit, which permits the use of a smaller inductor. The MAX1676 comes in a 10-pin µMAX package and features an adjustable current limit and circuitry to reduce inductor ringing.
