Instructions for HT6542B
Power Supply Connection:
- Connect the positive terminal of the power supply to VDD and the negative terminal to GND.
- Ensure the supply voltage is within the operating range (2.0V to 5.5V).
Standby Mode:
- To enter standby mode, set the control pin to a low state. The device will consume minimal current (approximately 0.1 μA at 3V).
Active Mode:
- Set the control pin to a high state to activate the device. The operating current in this mode is approximately 4.0 mA.
Output Configuration:
- The output voltage is nominally 3.3V under no load conditions. Ensure proper load regulation for stable operation.
Frequency and Duty Cycle Settings:
- Adjust the external components connected to the frequency and duty cycle pins to set the desired values within the operational ranges (300 kHz to 3000 kHz for frequency, and 0.1 to 0.9 for duty cycle).
Safety Considerations:
- Do not exceed the maximum ratings specified in the parameter table to avoid damage to the device.
- Ensure adequate heat dissipation if operating at higher currents or frequencies.
Troubleshooting:
- If the output voltage does not meet expected values, check the power supply connections and ensure all external components are correctly installed and functioning.
