MAX878L Overview
Key Specifications
Key Features
- They require only three external components-an inductor (typically 22µH) and two capacitors
- This eliminates the current drain associated with conventional step-up converters when off or in shutdown
- High-frequency operation (up to 150kHz) allows the use of small, surface-mount inductors with values of 10µH or less
- Supply current is 190µA under no load and only 20µA in standby mode; supply voltage can range from 1V to 4.5V (1 to 3 cells)
- With a 2V input, the devices typically deliver 200mA at 5V, or 300mA at 3V
