STMicroelectronics PM6613N
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.| Part No. | PM6613N |
