The recommended PCB layout for the TSC426CPA+ is to keep the input and output traces as short as possible, and to use a solid ground plane to reduce noise and EMI. Additionally, it's recommended to place a 10uF capacitor between the VCC and GND pins to filter out noise.
To ensure the TSC426CPA+ is operating within its recommended operating conditions, make sure the input voltage is within the range of 2.7V to 5.5V, the ambient temperature is within the range of -40°C to +125°C, and the output current does not exceed 100mA.
The EN (Enable) pin on the TSC426CPA+ is used to enable or disable the device. When the EN pin is pulled high, the device is enabled and operates normally. When the EN pin is pulled low, the device is disabled and enters a low-power shutdown mode.
The output voltage of the TSC426CPA+ can be calculated using the following formula: VOUT = (R1/R2) * (VIN - VREF), where R1 and R2 are the resistors connected to the FB pin, VIN is the input voltage, and VREF is the internal reference voltage (1.25V).
The maximum input voltage that can be applied to the TSC426CPA+ is 6V. Exceeding this voltage may damage the device.
