Product Information
Product Overview
The MAX8640ZELT12+T is a tiny 500mA, 4MHz/2MHz synchronous step-down DC-DC converter in 6 pin µDFN package. This step-down converter is optimized for applications where small size, high efficiency and low output ripple are priorities. It utilizes a proprietary PWM control scheme that optimizes switching frequency for high efficiency with small external components and maintains low output ripple voltage at all loads. It switches up to 4MHz to allow a tiny 1µH inductor and 2.2µF output capacitor. Output current is up to 500mA while typical quiescent current is 28µA. Factory-preset output voltages from 0.8V to 2.5V eliminate external feedback components. Internal synchronous rectification greatly improves efficiency and replaces the external Schottky diode required in conventional step-down converters. Internal fast soft-start eliminates inrush current so as to reduce input capacitor requirements. It is used in microprocessor/DSP core power and I/O power.
- Supply voltage range is 2.7V to 5.5V
- Operating temperature range from -40°C to 85°C
- Initial accuracy of ±1%
- Low output ripple at all loads
- Ultrasonic skip mode down to 1mA loads
- Ultra fast line and load transient response
- Fast soft start eliminates inrush current
- Typical thermal shutdown of +160°C
