Pinout
1. Pin 1 (V+): Positive supply voltage input.
2. Pin 2 (GND): Ground connection.
3. Pin 3 (D1): Driver output 1.
4. Pin 4 (D2): Driver output 2.
5. Pin 5 (OSC): Oscillator control input. This pin can be used to adjust the frequency or synchronize the oscillator.
6. Pin 6 (REF): Reference voltage output.
7. Pin 7 (SHDN): Shutdown input. A logic high or low on this pin will enable or disable the device.
8. Pin 8 (V-): Negative supply voltage input.
The MAX253ESA+ functions primarily as a high-frequency, push-pull transformer driver, which is used to step-up, step-down, or invert voltages by driving a transformer. This makes it suitable for applications requiring isolated power, such as in communication interfaces and other applications needing voltage isolation.
