MAX879
Key Features
- The MAX877 delivers a regulated 5V output from 2.5V to 6.2V inputs
- The MAX878 generates pin-selectable voltages of 3.0V or 3.3V from 1.5V to 6.2V inputs
- The MAX879 output can be adjusted from 2.5V to 6V via an external resistor divider from 2.5V to 6.2V inputs
- In shutdown, the active rectifier disconnects the output from the source
- This stops the current drain from input to output associated with conventional step-up converters
- High-frequency operation (up to 300kHz) allows the use of small surface-mount inductors
- Supply current is 195µA under no load, and only 20µA in shutdown mode
- For 1-cell (1V) step-up converters with similar performance and the same pinout, refer to the MAX777/MAX778/MAX779 data sheet
