What are the key features of TPS61200DRCR?
- Ultra-low 0.3 V minimum input voltage enables operation from nearly depleted single-cell Li-ion or alkaline batteries
- 1.3 A integrated switch current with current-mode PWM control delivers high efficiency up to 96% across load range
- Down Mode operation allows output voltage to smoothly follow input below regulated setpoint, preventing output collapse during battery discharge
What is TPS61200DRCR used for?
TPS61200DRCR is ideal for single-cell Li-ion and alkaline-powered portable devices where the battery voltage can drop below the required system rail, such as wireless sensor nodes, Bluetooth beacons, and handheld instruments that need 3.3 V from a battery that may discharge down to 0.3 V. Its adjustable output from 0.3 V to 5.5 V and 10-pin 3x3 mm QFN footprint suit space-constrained wearable electronics and IoT edge devices. The Down Mode feature also makes it attractive for energy harvesting applications powered by thermoelectric generators or small solar cells with variable open-circuit voltage.

Frequently Asked Questions
How low can the input voltage go on TPS61200DRCR, and what output voltages can it regulate to?
TPS61200DRCR operates from a minimum input voltage of 0.3 V, which is lower than most competing boost converters, and can regulate an adjustable output from 0.3 V up to 5.5 V using an external resistor divider. This makes it suitable for single-cell alkaline batteries that discharge to 0.8 V and Li-ion cells that reach as low as 2.7 V under load.
What is the Down Mode feature in TPS61200DRCR and when is it useful?
Down Mode allows TPS61200DRCR to pass the input voltage through to the output when the input rises above the regulated output setpoint, preventing an unregulated overvoltage condition. This is useful in energy harvesting designs where the source voltage is unpredictable, and in battery-powered systems where the rail must not collapse when the battery briefly exceeds the 3.3 V output target.
What switch current rating does TPS61200DRCR provide, and how does that affect inductor selection?
TPS61200DRCR integrates switches rated at 1.3 A peak current, which allows use of a small 2.2 uH to 4.7 uH inductor with a current rating of at least 1.5 A saturation current. Selecting the right inductor is critical because undersized saturation current causes efficiency drop and output voltage droop at high load currents above 500 mA.
How does TPS61200DRCR compare to TPS61221 for ultra-low input voltage energy harvesting?
TPS61200DRCR accepts inputs down to 0.3 V versus TPS61221 minimum of 0.7 V, making TPS61200DRCR the better choice for thermoelectric generators and nearly depleted cells. However, TPS61221 offers a fixed output with smaller external component count. For applications needing adjustable output between 0.3 V and 5.5 V from a sub-0.7 V source, TPS61200DRCR is the preferred solution.
