Texas Instruments: TPS61200EVM-179 Evaluation Module

Kit Overview

The Texas Instruments TPS61200EVM-179TPS61200EVM-179 is an evaluation module for the TPS61200TPS61200 low input voltage synchronous boost converter. The multiProductLinkTPS61200 provides a power supply solution for products powered by either a single-cell, two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-Ion or Li-polymer battery.

• The TPS61200EVM-179TPS61200EVM-179 is specially designed and optimized to operate from a single-cell, two-cell, or three-cell alkaline, NiCd or NiMH, as well as a one-cell Li-Ion or Li-polymer battery.
• It is also used in single-cell fuel cell or solar cell battery applications where the input voltage is as low as 0.3V.
• The TPS61200EVM-179TPS61200EVM-179 operates from a 0.3V to 5.5V (starts up ³ 0.5V) input rail and provides a single output voltage up to 5.5V.

The TPS6120xTPS6120x devices provide output currents of up to 600 mA at a 5-V output, while using a single-cell Li-Ion or Li-Polymer battery and discharges it down to 2.6 V. The boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters the Power Save mode to maintain a high efficiency over a wide load current range. The Power Save mode can be disabled, forcing the converter to operate at a fixed switching frequency. The average input current is limited to a maximum value of 1500 mA. The output voltage is programmed by an external resistor divider, or is fixed internally on the chip. The converter can be disabled to minimize battery drain. During shutdown, the load is completely disconnected from the battery.

Key Applications:
All Single-Cell, Two-Cell and Three-Cell Alkaline, NiCd or NiMH or Single-Cell Li Battery Powered Products, Fuel Cell And Solar Cell Powered Products, Portable Audio Players, PDAs, Cellular Phones, Personal Medical Products, White LED Driver
