The TLV61047-Q1 is a high-voltage, non-synchronous boost converter that integrates a 200mΩ low side power switch to provide an easy use and small size power design. The TLV61047-Q1 has a wide input voltage range from 1.8V to 20V and output voltage covers up to 28V with 2.2A switch current capability.

The TLV61047-Q1 uses adaptive constant off-time peak current control topology to regulate the output voltage. At heavy to light load condition, the TLV61047-Q1 works in pulse width modulation (PWM) mode until trigger the minimum peak current (typical 300mA). At lighter load condition , the devices work in pulse frequency modulation (PFM) mode to improve the efficiency and ripple performance.

The quasi-constant switching frequency is internally set to 2.4MHz, allowing the use of extremely small surface mount inductor and capacitors. The TLV61047-Q1 has built in 2.5ms soft start to minimize the inrush current during start-up. Additional features include internal compensation, cycle-by-cycle current limit, and thermal shutdown.

The TLV61047-Q1 is available in an SOT-23-5 DDC package.
