Applications

The TPS62004DGS can be used in a variety of applications. It is most often used in low power applications such as automotive electronics, medical devices, industrial applications and consumer electronics.

• Automotive applications – navigation, audio, cameras, sensors, etc.
• Medical applications – patient monitoring equipment, patient safety systems, etc.
• Industrial applications – instrumentation, process control, etc.
• Consumer applications – mobile devices, wearables, etc.

Working Principle

The TPS62004DGS is a DC-DC switching converter that operates by switching a MOSFET on and off rapidly at a frequency determined by an internal oscillator. When the switch is on, energy stored in the inductor is transferred to the output capacitor and the output voltage is boosted. When the switch is off, energy is pumped into the inductor and replenishes the energy stored in the output capacitor. This cycle is repeated many times per second and the output voltage stays within a certain range.

The TPS62004DGS can be used in a variety of topologies, including buck, inverted buck, flyback, inverting buck-boost, and buck-boost in both continuous conduction mode (CCM) and discontinuous conduction mode (DCM). The device has a wide input voltage range (3V to 20V) and an adjustable output voltage range (0.8V to 5.5V). It also has an I2C interface that can be used to adjust the output voltage on the fly. The device also features integrated over-current, short-circuit, over-voltage and thermal protection.
