TPS60140

illustrate

The TPS6014x boost, regulated charge pump generates an input voltage range of 3.6 V from 1.8 V to 5 V ± 4% output voltage. These devices are usually made up of two alkaline batteries, NiC, NiMH or supplied with at least 100 mA from a 2-V input and output. Only four external capacitors are required to set up a complete triple frequency voltage charge pump.

The device uses adjustment pulses to skip the output of the topology. The controller is optimized to output the full minimum output voltage ripple current range. Output peak current, therefore, output voltage ripple is greatly reduced compared to traditional pulses skipping the topology of adjusting the output impedance of a charge pump. The maximum output resistance at light loads is limited to ensure low quiescent current.

characteristic
