TPS61202DRCT Datasheet PDF - TI

●The TPS61202DRCT is a 0.3V Input Voltage Boost Converter with 1.3A switches and "Down Mode" that provide 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. It is also used in fuel cell or solar cell powered devices where the capability of handling low input voltages is essential. Possible output currents depend on the input to output voltage ratio. The boost converter is based on a fixed frequency, pulse-width-modulation 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 1500mA. The converter can be disabled to minimize battery drain.

● More than 90% efficiency

● Automatic transition between boost mode and down conversion mode

● Less than 55µA device quiescent current

● Start-up into full load at 0.5V input voltage

● Programmable under-voltage lockout threshold

● Output short-circuit protection under all operating conditions

● Fixed and adjustable output voltage options from 1.8 to 5.5V

● Power save mode for improved efficiency at low output power

● Forced fixed frequency operation possible

● Load disconnect during shutdown

● Over-temperature protection

● Green product and no Sb/Br

●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.
