3 Description
The TPS6101x devices are boost converters intended
for systems that are typically operated from a single-
or dual-cell nickel-cadmium (NiCd), nickel-metal
hydride (NiMH), or alkaline battery.
The converter output voltage can be adjusted from
1.5 V to a maximum of 3.3 V, by an external resistor
divider or, is fixed internally on the chip. The devices
provide an output current of 200 mA with a supply
voltage of only 0.9 V. The converter starts up into a
full load with a supply voltage of only 0.9 V and stays
in operation with supply voltages down to 0.8 V.
The converter is based on a fixed frequency, current
mode, pulse-width-modulation (PWM) controller that
goes automatically into power save mode at light
load. It uses a built-in synchronous rectifier, so, no
external Schottky diode is required and the system
efficiency is improved. The current through the switch
is limited to a maximum value of 1300 mA. The
converter can be disabled to minimize battery drain.
During shutdown, the load is completely isolated from
the battery.
An autodischarge function allows discharging the
output capacitor during shutdown mode. This is
especially useful when a microcontroller or memory is
supplied, where residual voltage across the output
capacitor can cause malfunction of the applications.
When programming the ADEN-pin, the autodischarge
function can be disabled. A low-EMI mode is
implemented to reduce interference and radiated
electromagnetic energy when the converter enters
the discontinuous conduction mode. The device is
packaged in the micro-small space saving 10-pin
MSOP package. The TPS61010 is also available in a
3 mm x 3 mm 10-pin QFN package.
