illustrate

The TPS6100x devices are typically used as pseudo-boost converters for single or two nickel-cadmium (NiCd), nickel metal hydride (NiMH), or alkaline battery-powered systems. The converter output voltage can be adjusted from 1.5 V to 3.3 V maximum and provides a minimum of 100 mA output from a single cell and two 250 mA current from the battery. The converter starts, inputs a 0.9 V supply voltage, and maintains an operating voltage low of 0.8 with a full load of five

The converter is based on a fixed-frequency, current-mode pulse-width modulation (PWM) controller that enters power-saving mode at low load currents. The current through the switch is limited to 1100 mA max, depending on the output voltage.

characteristic

• The start-up supply voltage is up to 0.9 V and the low full load is over the entire temperature range
