Features
The MAX629ESA includes an internal current limit and thermal shutdown for enhanced protection. Its low quiescent current (typically 110µA) ensures minimal battery drain in portable applications. The converter supports a fixed-frequency operation for predictable EMI performance.
Available in an 8-pin SOIC package, the MAX629ESA is designed for compact, space-constrained designs. It is well-suited for applications requiring consistent voltage output from a low-voltage source, such as LCD bias supplies, portable devices, and backup power systems.
Pinout
1. Pin 1 (IN): Input Supply Voltage. Connects to the power source.
2. Pin 2 (FB): Feedback. Connects to the output voltage divider to set the output voltage.
3. Pin 3 (SHDN): Shutdown. A low voltage on this pin shuts down the converter, reducing the supply current.
4. Pin 4 (GND): Ground. Common ground reference for all signals.
5. Pin 5 (LX): Inductor Connection. Connects to the inductor and the anode of the Schottky diode.
6. Pin 6 (REF): Reference Voltage Output. Provides a reference voltage for external components.
7. Pin 7 (COMP): Compensation. Connects to a compensation network to stabilize the control loop.
8. Pin 8 (PGND): Power Ground. Separate ground for power connections.
This configuration allows the MAX629ESA to efficiently step up low input voltages to a higher level, suitable for various applications requiring increased voltage.
