Note: Use Ceramic capacitors (C1,C2) with good high frequency characteristics.

Note: Ceramic capacitors (C1,C2) should be connected between pin 1 (V_DD1) and pin 2

(GND1) for V_DD1and between pin 16 (V_DD2) and pin 15 (GND2) for V_DD2, and should

be the layout on the IC as close as possible (less than 10mm).

Otherwise, the IC may not switch properly.

8.2. IC Startup Procedure

8.2.1. Output Enable Function

Output signal Enable / Disable control is possible by controlling pin 7 (EN1 pin) and pin 10 (EN2 pin) to

High or Low.

To enable output, set pin 7 (EN1 pin) and pin 10 (EN2 pin) to High or OPEN.

By setting pin 7 (EN1 pin) to Low, VO1 to VO3 can be disabled, and by setting pin 10 (EN2 pin) to Low,

VO4 can be disabled.

Note: The absolute maximum ratings of a semiconductor device are a set of specified parameter

values, which must not be exceeded during operation, even for an instant.

If any of these rating would be exceeded during operation, the device electrical

characteristics may be irreparably altered, and the reliability and lifetime of the device can

no longer be guaranteed. Moreover, these operations with exceeded ratings may cause

break down, damage, and/or degradation to any other equipment. Applications using the

device should be designed such that each maximum rating will never be exceeded in any

operating conditions.

Before using, creating, and/or producing designs, refer to and comply with the precautions

and conditions set forth in this document.

Note 1: Maximum voltage must not exceed 6V
