Features
1. Low Operating Voltage: Functions effectively with input voltages ranging from 1.5V to 5.5V, making it suitable for battery-powered applications.
2. Output Current: Delivers up to 25 mA, meeting the needs of low-power applications.
3. Efficiency: Offers high efficiency, reducing power loss and heat generation in the system.
4. Compact Package: Available in a small SOT-23 package, which is ideal for space-constrained applications.
5. Low Quiescent Current: Consumes minimal quiescent current (typically around 100 µA), enhancing battery life in portable devices.
6. No Inductors Required: Simplifies design and reduces cost and size because it doesn't require external inductors.
7. Shutdown Feature: Includes a shutdown mode to further conserve power when the device is not in use.
8. Wide Temperature Range: Operates over a wide temperature range, ensuring reliability in various environmental conditions.
These features make the MAX828EUK suitable for applications like LCD biasing and general-purpose negative voltage generation.
Pinout
The pin configuration is as follows:
1. GND: Ground pin.
2. CAP+: Positive terminal for the charge-pump capacitor.
3. VOUT: Output pin where the negative voltage is generated.
4. VIN: Input voltage pin.
5. CAP-: Negative terminal for the charge-pump capacitor.
The MAX828EUK operates over a supply voltage range of 1.5V to 5.5V and is often used in situations where a negative voltage is required but only a positive supply is available, such as in portable devices, LCD panels, and battery-powered applications.
