TITPS61200DRCR
Overview
The TPS61200DRCR is a highly efficient synchronous boost converter designed for power solutions from low-voltage sources such as single-cell alkaline, NiCd, NiMH, or Li-ion batteries. It features an exceptionally low input voltage capability, starting up into full load at just 0.5V and operating down to 0.3V once running. The device includes a down-conversion mode that maintains regulation even when the input voltage exceeds the target output voltage.
Why Choose This Part
The primary advantage is the industry-leading 0.3V minimum operating voltage, allowing for maximum energy extraction from depleted batteries or low-voltage transducers. It integrates a 1.2A switch and provides a true load disconnect during shutdown to prevent battery drain. The automatic transition to down-conversion mode ensures seamless regulation regardless of whether the battery is fresh or nearly empty.
Applications
Key Specifications
Getting Started
Designers can evaluate this part using the TPS61200EVM-179 evaluation module. When designing the PCB layout, keep the power ground and signal ground separate and minimize the trace length between the input capacitor, inductor, and the VINA/VOUT pins to reduce EMI. A standard 4.7uH to 10uH inductor is typically recommended for most 1.25MHz to 1.65MHz switching applications.
