T6319A
Functional Description
The T6319A regulated charge pump provides a regulated output voltage for input voltages ranging
from less than the output to greater than the output. This is accomplished by automatic mode
switching within the device.
PROTECTION
The regulator has thermal shutdown circuitry that protects it from damage caused by overload
conditions. The thermal protection circuitry disables the output when the junction temperature
reached approximately 140°C, allowing the device to cool. When the junction temperature cools to
approximately 130°C, the output circuitry is automatically reenabled. Continuously running the
regulator into thermal shutdown can degrade reliability.
SHUTDOWN MODE
A control pin on the regulator can be used to place the device into an energy-saving shutdown mode.
In this mode, the output is disconnected from the input as long as V
IN
is greater than or equal to
minimum V
IN
.

Revision: A
Charge Pump Efficiency
The core of the T6319A is a regulated output voltage doubling charge pump. The efficiency (
η
) or
an deal voltage doubling charge pump an typically be expressed as the output power divided by the
input power:
η
= P
OUT
/P
IN
In addition, with anideal voltage doubling charge pump, the output current may be expressed as half
the input current. The expression to define the ideal efficiency (
η
) can be rewritten as:
η
= P
OUT
/P
IN
= V

x I
