1. Soft start time set up

If you wish to lengthen soft start time we recommend that you use the C or D versions of the series which

have soft start time externally set up.

In order to achieve a value for fzfb within the range of 0.1kHz to 20kHz, we recommend that values for

shown on the graph below. Please select combinations of values as close to the fzfb = 10kHz line as possible.

■Directions for use

GNotes on Use

Take ample care to ensure that none of the IC's, nor the external component's, absolute maximum ratings are exceeded.

Be extremely careful when selecting parts and do not limit your reference to the specifications and characteristics for the DC/DC converter

alone. The IC also depends, to a great extent, upon the external components.

Arrange the peripherals in the environs of the IC. In order to reduce wiring impedance, use short, thick wires. In particular, wire the load

capacitor as close as possible and strengthen the ground wiring sufficiently.

Ground current during switching may cause the IC's operations to become unstable due to changes in ground voltage, so please strengthen the

IC's GND pin surroundings.
