■General Description

■Features

The XC6367/68 series are multi-functional step-up DC/DC converter

controllers with built-in high speed, low ON resistance drivers.

Large output currents are possible using an externally connected

transistor, coil, diode and condenser.

Input voltage range

: 0.9V~10V

Operating voltage range : ±.0V~10V

Output voltage range

Oscillator frequency

: 1.5V~6.5V programmable in 0.1V

steps (±±.5ꢀ%

Output voltage is selectable in 0.1 steps within a 1.5V ~ 6.5V range

(±±.5ꢀ%. ꢁor output voltages outside this range, we recommend this ꢁF

version, which has a 1.0V internal reference voltage. Using this version,

the required output voltage can be set-up using ± external resistors.

With a 300kHz switching frequency, the size of the external components

can be reduced.

Control switches from PWM to PꢁM during light loads with the XC6368

(PWM/PꢁM switchable% and the series is highly efficient from light loads

to large output currents.

Package

Soft start time of XC6367/68A, F, and C series is internally set to

10msec and XC6367/68C, D, and ꢁ series regulate soft start time by

connecting resistors and capacitors exteranally.

During stand-by time (CE pin "Low"%, current consumption is reduced to

less than 0.5µA.

■Directions for use

ꢀNotes on Use

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

Fe 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.

ꢀExternal Components

■�External Components

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.

Soft start time (TSS% is between MIN & MAX, as indicated in the graphs below, so please select soft start

condenser capacitance (CSS% to suit your application.
