TPS61013

illustrate

The TPS6101x devices are typically used as a pseudo-boost converter for single or two-cell nickel-cadmium (NiCd), nickel metal hydride (NiMH), or alkaline battery-powered systems.

The converter output voltage can be adjusted from 1.5 V to 3.3 V maximum by an external resistor divider, or fixed inside the chip. These devices provide only five output currents of 200 mA for a supply voltage converter that starts at a supply voltage of only 0.9 V and maintains a full load of 0.8 and 0.9 with a supply voltage converter starting

The converter is based on a fixed frequency, current mode, pulse width modulation (PWM) controller enters the power supply and automatically saves in light load mode. It uses a built-in synchronous rectifier, therefore, the elimination of external Schottky diodes is necessary and the efficiency of the system is increased.

characteristic

• Integrated synchronous rectifier power maximum conversion efficiency ("95%)
• The start-up supply voltage is up to 0.9 V for full load and low to operate at up to 0.8 volts
• 200 mA outputs a supply current of 0.9 - V
• Power saving mode to improve efficiency at low output current
• Autodischarge allows the output capacitor to be discharged during shutdown
• The quiescent current of the device is less than 50 microamps
• Easy to use by isolating from the battery load in converter shutdown
• Integrated anti-ringing switch across inductors
• Integrated low battery comparison
• Micro-small 10-pin MSOP or 3 mm x 3 mm QFN package
• EVM Availability (TPS6101xEVM-157)
• apply
  • All single or dual battery operation is different from Internet audio players, pagers, portable medical diagnostic equipment, remote control products, wireless headphones
