)
The MPQ3413 can start up from an input voltage
(VIN) as low as 2.8V, and provides inrush current
limiting and output short-circuit protection (SCP).
The integrated P-channel synchronous rectifier
(SR) improves efficiency and eliminates the
requirement of an external Schottky diode. The
MPQ3413’s P-channel MOSFET disconnects
the output from the input when the MPQ3413
shuts down. The output disconnect feature
allows the output to be discharged completely,
allowing the MPQ3413 to draw a supply current
below 1μA in shutdown mode.
The 2.2MHz switching frequency (fSW) allows for
smaller external components, while the internal
compensation and soft start (SS) minimize the
external component count. These features result
in a compact solution across a wide current load
range.
APPLICATIONS
Single-Cell, Li Battery Backup
Automotive Secondary Regulation
The MPQ3413 features an integrated power
MOSFET that supports an 5V output voltage
(VOUT) and a peak switching current above 1.5A.
