Altech recommends a 4-layer PCB with a dedicated ground plane and thermal vias to ensure efficient heat dissipation. A minimum of 2 oz copper thickness is recommended for the power traces.
The 934099101 has built-in overvoltage protection (OVP) and overcurrent protection (OCP) circuits. OVP is set to 30V, and OCP is set to 3A. The device will automatically shut down in case of an overvoltage or overcurrent event.
Altech recommends using a 10uF, 50V, X7R ceramic capacitor as the input capacitor. This value provides a good balance between filtering and stability.
The 934099101 is rated for operation up to 85°C. However, the device's power rating must be derated by 1.5% per degree above 60°C. For example, at 80°C, the power rating would be reduced by 30%.
The typical start-up time of the 934099101 is 10ms. The device has a built-in soft-start circuit that ramps up the output voltage over a period of 5ms to prevent inrush currents.
