10 Power Supply Recommendations

The VDD operating range allows direct connection to converter outputs from 5 V to 24 V. Since the driver and control share the same VDD and ground, it is recommended to place a good quality ceramic capacitor as close as possible to VDD and GND pins. To reduce VDD noise and eliminate high-frequency ripple current injected from the converter output, it is recommended to place a small resistance of 2.2 Ω to 10 Ω between the converter output and VDD. The device can tolerate VDD rise times from 100 µs to very long rise times typical of constant current chargers. The start-up sequence will always be as shown in Figure 12. VDD can be connected to an external bias to extend the device's operating range to be compatible with converter output voltages below 3.5 V or above 24 V.
