■GENERAL DESCRIPTION
■FEATURES
The XC6365/66 series are multi-functional step-down DC/DC
converters with built-in high speed, low ON resistance drivers. An
connected transistor, coil, diode and capacitor.
Input Voltage Range : 2.2V~10V (VOUT type)
Output Voltage Range : 1.5V ~ 6.0V programmable in
100mV steps (±2.5%)
Oscillation Frequency : 300kHz (±15%)
Output voltage is programmable in 100mV steps between 1.5V to
6.0V (VOUT) (±2.5% accuracy). Further, with 1.0V of standard
voltage supply internal and using externally connected
components, output voltage can be set up freely (FB).
With a 300kHz switching frequency, the size of the external
components can be reduced.

■NOTES ON USE
1. Take ample care to ensure that none of the IC's, nor the external component's, absolute maximum ratings are exceeded.
2. 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.
3. 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.
4. 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.
●External Components
1. Setting soft start time
To set a longer soft start time, please use XC6365C or XC6365D series which soft start function is externally set up.
For the measurement of soft start time TSS, the time is needed to be between the max. and the min. value indicated in the
chart below. Please set a soft start capacitor CSS according to the application.
2. Setting RFB1 and CFB
fzfb=1 ÷ (2 π × CFB × RFB1)
As the combination of RFB1 and CFB enable to set fzfb between 0.5kHz to 20kHz, within the realm of fzfb=0.5kHz to
fzfb=20kHz as the chart below can be effective.
Under normal condition, please set the combination to configure around fzfb=10kHz.
