ꢀTheꢀ constantꢀ frequencyꢀ 2ꢀ MHz charge pump allows small 1ȝF
ceramic capacitorsꢀto be used.
Maximum output loads of up to 100 mA can be supported over a
wide range of input supply voltages (2.7 V to 4.5 V) making the device
ideal for batteryïpowered applications.

A shutdown control input allows the device to be placed in
powerïd own mode, reducing the supply current to less than ꢁȝ$.
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 powerïup.

Pin Functions
IN is the power supply. During normal operation the device
draws a supply current which is almost constant. A very
brief interval of nonïconduction will occur at the switching
frequency. The duration of the nonïconduction interval is
set by the internal nonïoverlapping “breakïbeforeïmake”
timing. IN should be bypassed with a 1 F to 4.7 F low
ESR (Equivalent Series Resistance) ceramic capacitor
For filtering, a low ESR ceramic bypass capacitor (1 F)
in close proximity to the IN pin prevents noise from being
injected back into the power supply.
a low ESR ceramic bypass capacitor (1 F to 4.7 F) in close
proximity to the OUT pin. The ESR of the output capacitor
will directly influence the output ripple voltage.
When the shutdown mode is entered, the output is
immediately isolated from the input supply, however, the
output will remain connected to the internal feedback
resistor network (400 k ). The feedback network will result
in a reverse current of 10 A to 20 A to flow back through
the device to ground.
Whenever the device is taken out of shutdown mode, the
output voltage will experience a slew rate controlled
powerïup. Full operating voltage is typically achieved in
less than 0.5 msec.
SHDN is the logic control input (Active LOW) that places
the device into shutdown mode. The internal logic is CMOS
and the pin does not use an internal pullïdown resistor. The
SHDN pin should not be allowed to float.
CPOS, CNEG are the positive and negative connections
respectively for the charge pump flying capacitor. A low
ESR ceramic capacitor (1 F) should be connected between
these pins. During initial powerïup it may be possible for the
capacitor to experience a voltage reversal and for this reason,
avoid using a polarized (tantalum or aluminum) flying
capacitor.
GND is the ground reference for all voltages on :ꢀꢁꢂꢃꢃïꢁ
devices.
OUT is the regulated output voltage to power the load.
During normal operation, the device will deliver a train of
current pulses to the pin at a frequency of 2 MHz. Adequate
filtering on the pin can typically be achieved through the use

Application Information
Ceramic Capacitors
Ceramic capacitors of different dielectric materials lose
their capacitance with higher temperature and voltage at
different rates. For example, a capacitor made of X5R or
X7R material will retain most of its capacitance from – 40$C
to 85$C whereas a Z5U or Y5V style capacitor will lose
considerable capacitance over that range.
Z5U and Y5V capacitors may also have voltage
coefficient causing them to lose 60% or more of their
capacitance when the rated voltage is applied. When
comparing different capacitors it is often useful consider the
amount of achievable capacitance for a given case size rather
than discussing the specified capacitance value. For
example, over rated voltage and temperature conditions, a
1 F, 10 V, Y5V ceramic capacitor in an 0603 case may not
provide any more capacitance than a 0.22 F, 10 V, X7R
available in the same 0603 case. For many W-5200/
:ꢀꢁꢂꢃꢃï5 applications these capacitors can be considered
roughly equivalent.
