HIGH-EFFICIENCY, 1-CELL AND 2-CELL BOOST CONVERTERS

An autodischarge function allows discharging the out-

put 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 program-

ming 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 conduc-

tion mode. The device is packaged in the micro-small

space saving 10-pin MSOP package.

DESCRIPTION

OUTPUT CURRENT

100

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 volt-

age 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.

VBAT = 2.4 V,

= 3.3 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.
