Instructions for Use

1. Power Supply Connection:

   • Connect the positive supply voltage (Vcc) to Pin 8.
   • Connect the ground (GND) to Pin 4.

2. Oscillator Configuration:

   • Connect an external resistor (Rt) between Pin 6 (RT/CT) and ground.
   • Connect an external capacitor (Ct) between Pin 6 (RT/CT) and Pin 5 (GND).
   • The oscillator frequency is given by ( f = frac{1.1}{R_t cdot C_t} ).

3. Output Configuration:

   • The SG3525AP013TR has two output channels (OutA and OutB) on Pins 11 and 14, respectively.
   • These outputs can be connected to the gates of MOSFETs or other switching devices.

4. Error Amplifier:

   • Connect the inverting input of the error amplifier (Pin 1) to the feedback signal.
   • Connect the non-inverting input of the error amplifier (Pin 2) to the reference voltage (Vref) which is typically 2.5V.
   • The reference voltage is available on Pin 3.

5. Shutdown Function:

   • To enable the shutdown function, connect a logic high signal to Pin 10 (Shutdown).
   • To disable the shutdown function, connect a logic low signal to Pin 10 (Shutdown).

6. Dead Time Adjustment:

   • The dead time can be adjusted using an external capacitor connected to Pin 9 (Dead Time Adjust).

7. Thermal Management:

   • Ensure proper heat dissipation by using a heatsink if necessary, especially when operating at high power levels.

8. Storage and Handling:

   • Store the device in a dry environment to prevent moisture damage.
   • Handle with care to avoid static discharge, which can damage the device.
