Description:Utilizing proprietary process technology to achieve high operating temperature up to 125°C; Compact half pitch, mini-flat, 4-pin package (1.27mm lead pitch, 2.4mm maximum standoff height); > 5mm creepage and clearance distance; High isolation voltage regulated by safety agency, UL1577, 3750 VAC RMS for 1 min. and DIN EN/IEC60747-5-2 (pending approval); Applicable to Infrared Ray reflow, 245°C; Guaranteed Current Transfer Ratio (CTR) specifications across full temperature range; CTR at very low input current
A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces as short as possible and away from noise sources.
Ensure the input voltage is within the recommended range (4.5V to 5.5V) and the output voltage is set to the desired level using the feedback resistors. Also, ensure the bias current is within the recommended range (1mA to 10mA).
The maximum allowable power dissipation for FODM8801A is 1.4W. Ensure the device is properly heat-sinked and the ambient temperature is within the recommended range (-40°C to 125°C).
Use a voltage regulator or a voltage supervisor to ensure the input voltage is within the recommended range. Also, consider adding overvoltage protection (OVP) and undervoltage protection (UVP) circuits to prevent damage to the device.
A 10uF to 22uF ceramic capacitor is recommended for input decoupling. The capacitor should be placed as close as possible to the input pin.
