The TLV61047 is a high voltage non-synchronous boost converter integrates a 200mΩ low side power switch to provide an easy use and small size power solution. The TLV61047 has a wide input voltage range from 2.6V to 20V and output voltage covers up to 28V with 2.2A switch current capability.

The TLV61047 uses adaptive constant off-time peak current control topology to regulate the output voltage. At heavy to light load condition, the TLV61047 works in pulse width modulation (PWM) mode until trigger the Ton min or minimum peak current (typical 20mA). At ultra light 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 either 1.6MHz (TLV61047) or 0.6MHz (TLV610471), allowing the use of extremely small surface mount inductor and capacitors. The TLV61047 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 is available in a SOT-23-5 DDC package.
