TEXAS INSTRUMENTS TPS61201DRCT Synchronous Boost (Step Up) Switching Regulator, Fixed, 300mV-5.5V In, 3.3V And 0.3A Out, SON-10

The TPS61201DRCT is a Boost Converter 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. 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. It provides output currents of up to 600mA at a 5V output, while using a single-cell li-ion or li-polymer battery and discharges it down to 2.6V. 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 1500mA.

• Automatic transition between boost mode and down conversion mode
• Programmable undervoltage lockout threshold
• Output short circuit protection under all operating conditions
• Power save mode for improved efficiency at low output power
• Forced fixed frequency operation possible
• Load disconnect during shutdown
• Overtemperature protection
• Green product and no Sb/Br
