SOT-5X3 (DRL)-6-2.56 mm² 1.6 x 1.6
SOT563 package (1.6mm x 1.6mm)
The TPS61299-Q1 is a synchronous boost converter with 95nA ultra-low quiescent current and average input current limit. The device provides a power solution for portable equipment with alkaline battery and coin cell battery. This device operates at high efficiency under light-load condition to achieve long operation time and average input current limit can avoid battery discharging with high current.
The TPS61299-Q1 has wide input voltage range from 0.5V to 5.5V and output voltage range from 1.8V to 5.5V. The average input current limit of this device is 1.2A. The TPS61299-Q1 with 1.2A current limit can support up to 500mA output current from 3V to 5V conversion and achieve approximately 94% efficiency at 200mA load.
The TPS61299-Q1 has optional fast-load transient performance at output voltage is 4.5V, 5V, or 5.5V.
The TPS61299-Q1 supports true shutdown function when it is disabled.
TThe TPS61299-Q1 offers a very small solution size with 1.6mm × 1.6mm SOT563 package.
