A thermal pad is recommended under the package to improve heat dissipation. A minimum of 2oz copper thickness and a thermal relief pattern is suggested. Refer to ROHM's application note for more details.
The device requires a soft-start circuit to prevent inrush current. A recommended power-up sequence is to apply VCC first, followed by EN (enable) pin. For power-down, disable EN first, then remove VCC.
The maximum allowed voltage on the input pins is VCC + 0.3V. Exceeding this voltage may cause damage to the device.
The device has built-in ESD protection, but additional external protection is recommended. Use a TVS diode or ESD protection IC on the input lines to ensure device safety.
The recommended operating frequency range is 100 kHz to 1 MHz. Operating outside this range may affect device performance and stability.
