The company said: "ZXGD3113 controls an external MOSFET, such
as a 100V16mΩn channel DMT10H015LPS configured as an ideal diode
." "The SOT26 size reduces the size of the
industry standard SO8 solution, and by operating at frequencies up to 250kHz, PSU designers
can use smaller Transformer. "
Proportional gate drive is implemented
.
Although it can also operate in discontinuous conduction mode and
critical conduction mode, it can quickly turn off synchronous mosfet in continuous conduction mode.
Other features include a 10mV threshold voltage, which can be used with low
RDSDS (on) and mosfets with peak source
and sink currents of 0.5A and 1.5A, respectively.
The operating
voltage range is 3.5V to 40V, allowing the chip to generate voltages as low as 3.5V, and to handle
a large number of overvoltage spikes on higher power rails, such as 24V. The quiescent current is
6.3mA.
