General Description

The XC9211/9212 series is a group of synchronous-rectification

type DC/DC converters with a built-in 0.6

Ω

P-channel driver

transistor and N-channel switching transistor, designed to allow

the use of ceramic capacitors. The ICs enable a high efficiency,

stable power supply with an output current of 400 mA to be

configured using only a coil and two capacitors connected

externally.

Minimum operating voltage is 1.8 V. Output voltage is internally

programmable in a range from 0.9 V to 4.0 V in increments of

0.1 V (accuracy:

2.0%). With the built-in oscillator, oscillation

frequency is selectable from 300 kHz, 600 kHz and 900 kHz to

make available the frequency best suited to your particular

application. As for operation mode, the XC9211 series is of a

synchronous-rectified PWM control type, while the XC9212

series can be manually switched between the PWM control

mode with synchronous rectification and the automatic

PWM/PFM switching control mode with non synchronous

rectification, allowing fast response, low ripple and high

efficiency over the full range of load (from light load to high

output current conditions). The soft start and current control

functions are internally optimized. During standby, all circuits

are shutdown to reduce current consumption to as low as 0.5

µA

or less. With the built-in U.V.L.O. (Under Voltage Lock Out)

function, the internal P channel driver transistor is forced OFF

when input voltage becomes 1.6 V or lower. Two types of

packages, 250 mW (SOT-25) and 100 mW (USP-6B), are

available depending on applications.
