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.
