Product Overview

The TPS61020DRCRG4 is a 96% Efficient Boost Converter with down-mode. It provides a power supply solution for products powered by a one-cell, two-cell or three-cell alkaline, NiCd or NiMH or one-cell Li-ion or Li-polymer battery. Output currents can go as high as 200mA while using a single-cell alkaline battery and discharge it down to 0.9V. The device can also be used for generating 5V at 500mA from a 3.3V rail or a Li-ion battery. The boost converter is based on a fixed-frequency, pulse width modulation (PWM) controller using a synchronous rectifier 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 maximum peak current in the boost switch is limited to a value of 800, 1500 or 1800mA depending on the version of the device.
  • 96% Efficient synchronous boost converter
  • Output voltage remains regulated when input voltage exceeds nominal output voltage
  • 25µA Typical device quiescent current
  • Fixed and adjustable output voltage options up to 5.5V
  • Power save mode for improved efficiency at low output power
  • Low battery comparator
  • Low EMI-converter (integrated anti-ringing switch)
  • Load disconnect during shutdown
  • Over-temperature protection
  • Green product and no Sb/Br

Applications

Power Management, Portable Devices, Audio, Multimedia, Communications & Networking, Medical, LED Lighting

Warnings

This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
