TPS60403

illustrate

The TPS6040x is a home that produces devices with a non-standard negative output voltage from an input range of 1.6 V to 5.5 voltage, and the device is usually preregulated by 5 V or 3.3 five, due to its wide input voltage range power rails, two or three NiCdm, NiMH or alkaline batteries, and a lithium-ion battery power supply they can also be used.

With only three external 1-μF capacitors, a complete DC/DC charge pump inverter needs to be established. The package is assembled in a 5-pin SOT23 package, and the complete converter can be built in a 50 square millimeter board area. The additional board area and the reduction in the number of components are achieved by replacing Schottky diodes, which typically require the activation function of the integrated circuit load.
