Description
The PM6613N is a high efficiency battery charger
with SMBus communication interface. It includes
a synchronous switching DC-DC converter with
N-channel high-side and low-side power
MOSFET drivers. The possibility to set the
switching frequency with SMBus by choosing one
of the two preset values of 350 kHz or 700 kHz
assures the best trade-off between power
conversion efficiency and PCB cost and size.
Integrated loop compensation network and soft-
start allow the reduction of the number of external
components.
The PM6613N integrates 2 charge pumps to drive
N-channel ACFET/RBFET and BATFET
MOSFETs.
The SMBus communication interface is used to
set the battery charge current and voltage.
The PM6613N charges 2 to 4 series Li-Ion or
LiFePO₄ cells, for mobile PC applications. It is
available in a compact VFQFPN 3x3 mm
package.
