PM6613N is a high efficiency battery charger with SMBus communication interface from STMicroelectronics. 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 switching noise.
The PM6613N is a high-efficiency battery charger designed for mobile PC applications such as UMPCs, MID devices, tablets, netbooks, and notebooks. It features a synchronous buck converter with N-channel RBFET and BATFET MOSFET selectors to drive 2 to 4 series Li-ion or LiFePO4 cells.
The device operates with an AC adapter input voltage range of 9 V to 24 V and supports a battery charge voltage range from 2.5 V to 18 V, offering +0.5% charge voltage accuracy. Key features include selectable switching frequencies of 350 kHz or 700 kHz via SMBus, integrated loop compensation, soft-start, and comprehensive protection against overvoltage, overcurrent, and short circuits.
