TPS61027DRCR (Texas Instruments) is a synchronous boost converter from the TPS6102x family with a fixed 5 V output and a 1500 mA switch current limit, in a 10-pin VSON package (3 x 3 mm).

• 96% efficiency · 0.9 V to 6.5 V input voltage range · fixed 5 V output
• 25 µA (typ) quiescent current · Power Save mode for improved efficiency at low output power
• Low battery comparator · load disconnect during shutdown · low-EMI converter (integrated anti-ringing switch)
• Overtemperature protection · output voltage remains regulated when the input voltage exceeds the nominal output voltage
