3 Description
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.
