ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended, and the thermal pad should be connected to a ground plane or a dedicated heat sink.
To ensure output voltage stability, it's essential to use a high-quality output capacitor with a low ESR (Equivalent Series Resistance) and a sufficient capacitance value (e.g., 10uF or more). Additionally, the input capacitor should be placed close to the VIN pin, and the output capacitor should be placed close to the VOUT pin.
Although the recommended input voltage range is 2.5V to 5.5V, the BD2240G-GTR can withstand a maximum input voltage of 6.5V for a short duration (less than 100ms) without damage. However, it's essential to ensure that the input voltage does not exceed 6.5V for extended periods to prevent damage or degradation.
The BD2240G-GTR is rated for operation up to 125°C, but it's essential to consider the derating of the output current and power dissipation at high temperatures. ROHM recommends reducing the output current and power dissipation by 50% when operating above 85°C to ensure reliable operation.
The power dissipation of the BD2240G-GTR can be calculated using the formula: Pd = (VIN - VOUT) x IOUT + (VIN x IQ), where IQ is the quiescent current. It's essential to consider the power dissipation and thermal management to prevent overheating and ensure reliable operation.
