Overview
The MAX641/MAX642/MAX643 step-up switching regulators are designed for minimum component DC-DC converter circuits in the 5mW to 10W range. Low-power applications require only an output filter capacitor and a small, low-cost inductor. An additional MOSFET or bipolar transistor is needed for high-power applications. Low battery detection circuitry is included on chip. The MAX641/642/643 are preset for +5V, +12V and +15V outputs, respectively. However, the regulators can be set to other levels by adding 2 resistors.
Applications
- Simple, High-Efficiency DC-DC Converters
- Uninterruptible Board-Level Power Supplies
- Power Conditioning for Battery Systems
- Portable Instruments and Communications
Key features
- Fixed +5V, +12V, ±15V Output Voltages
- Adjustable Output with 2 Resistors
- On-Chip Driver for High-Power External MOSFET
- 135μA Typ Operating Current
- 80% Typ Efficiency
- 8-Pin Narrow DIP and Narrow SO Packages
