TPS61014

illustrate

The TPS6101x device is a probo-boost converter for systems typically powered by single or two-cell nickel-cadmium (NiCd), nickel-metal hydride (NiMH), or alkaline batteries.

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

The converter is based on a fixed-frequency, current-mode, pulse-width modulation (PWM) controller that automatically saves the power supply in light load mode. It uses a built-in synchronous rectifier, so the need for an external Schottky diode is necessary and the efficiency of the system is improved.

characteristic

• Integrated synchronous rectifier power maximum conversion efficiency ("95%")
• The supply voltage starts into full load up to 0.9 V and operates at a low level of up to 0.8 volts
• 200 mA outputs 0.9 - V supply current
• Power-down 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 the converter shutdown
• Integrated anti-ringing switch spans inductance
• Integrated low battery comparison
• Miniature 10-pin MSOP or 3mm x 3mm QFN package
• EVM available (TPS6101xEVM - 157)
• apply
  • All single or dual battery operation differs from Internet audio players, pagers, portable medical diagnostic devices, remote control products, and wireless headphones
