CAT3200, CAT3200-5

Low Noise Regulated Charge Pump DC-DC Converter

DESCRIPTION

The CAT3200 and CAT3200-5 are switched capacitor

boost converters that deliver a low noise, regulated

output voltage. The CAT3200-5 gives a fixed regulated

5V output. The CAT3200 has an adjustable output

using external resistors. The constant frequency 2MHz

charge pump allows small 1

µF ceramic capacitors to

be used.

Maximum output loads of up to 100mA can be

supported over a wide range of input supply voltages

(2.7V to 4.5V) making the device ideal for battery-

powered applications.

FEATURES

s Constant high frequency (2MHz) operation

s 100mA output current

s Regulated output voltage (5V fixed CAT3200-5,

Adjustable CAT3200)

s Low quiescent current (1.7mA typ.)

s Input voltage operation down to 2.7V

s Soft start, slew rate control

s Thermal overload shutdown protection

s Low value external capacitors (1

µF)

s Foldback current overload protection

s Shutdown current less than 1

µA

s CAT3200-5 in low profile (1mm thin) 6-lead

SOT23 package

s CAT3200 in MSOP-8 package

Doc. No. 5002, Rev. E

APPLICATIONS

s 3V to 5V boost conversion

s White LED driver

s USB On-The-Go 5V supply

A shutdown control input allows the device to be

placed in power-down mode, reducing the supply

current to less than 1

µA.

In the event of short circuit or overload conditions, the

device is fully protected by both foldback current

limiting and thermal overload detection. In addition, a

soft start, slew rate control circuit limits inrush current

during power-up.

The CAT3200-5 is available in a 6-lead, 1mm max

thin SOT23 package. The CAT3200 is available in an

8-lead MSOP package.

s Local 5V supply from lower rail

s Battery backup systems

s Handheld portable devices
