SGM41603
I2C Controlled 10A Bidirectional Switched-Capacitor Converter
I2C Controlled 10A Bidirectional Switched-Capacitor Converter
GENERAL DESCRIPTION

The SGM41603 is an efficient 2:1 bidirectional switched-capacitor converter with integrated power switches. It can deliver 10A in forward direction (2:1 voltage divider) and 5A in the reverse direction (1:2 voltage doubler). This device allows using a 2S Li+ power source as a 1S Li+ solution by inserting it between the 2S battery pack and charger output, and saves the existing 1S power architecture that is powered from the same battery.

This 2-phase high switching frequency (1.5MHz, MAX) and inductor-less topology allow low profile design with small footprint. The high switching frequency also reduces the size and quantity of the required capacitors. Safe operation is assured by over-voltage, under-voltage, over-current and thermal protections. Interference is also minimized by the built-in frequency dithering option. This device can achieve 98.5% efficiency which is the highest in its class. Thermal management of such a low loss device is simple, which makes it an ideal choice for industrial, consumer, and medical applications.

The I2C interface allows flexible parameter settings including OCP, OVLO, switching frequency thresholds and soft-start currents and durations. The SGM41603 is available in a Green WLCSP-2.85×2.59-42B package.
