BD48K33G-TL Frequently Asked Questions (FAQs)

A recommended PCB layout for optimal thermal performance would be to use a large copper area on the top and bottom layers, connected to the thermal pad of the IC, and to use thermal vias to dissipate heat efficiently.
To ensure stable operation with a high-ESR output capacitor, it's recommended to add a small ceramic capacitor (e.g., 1uF) in parallel with the high-ESR capacitor to improve the overall capacitance and reduce the risk of oscillation.
The maximum allowed voltage on the EN pin is the same as the maximum supply voltage (VIN) of the device, which is 36V for the BD48K33G-TL.
While the BD48K33G-TL is rated for operation up to 125°C, it's essential to consider the derating of the device's performance and the potential for reduced lifespan at high temperatures. Consult the datasheet and ROHM's application notes for guidance on high-temperature operation.
The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
