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.
