TPS61200DRCR (Texas Instruments) is a low-input-voltage synchronous boost converter from the TPS6120x series, in the adjustable-output version and a 10-pin VSON package.

• 0.3 V to 5.5 V input · startup into full load at 0.5 V input · 1.8 V to 5.5 V output
• More than 90% efficiency · 300 mA at 3.3 V (VIN ≥ 2.4 V) and 600 mA at 5 V (VIN ≥ 3 V)
• Quiescent current less than 55 µA · automatic transition between boost mode and down conversion mode
• Programmable undervoltage lockout threshold · output short-circuit protection

Sold in packs of 10 units.
