Product Details

The MAX77932C is a standalone, dual-phase switched-capacitor converter with integrated power switches that delivers 8A output current and divides the input voltage by two. The IC is suitable for applications that utilize 2S Li+ batteries while powering circuitry that operates at 1S-equivalent voltage. It is also suitable for applications migrating from 1S to 2S battery configurations. The IC simplifies this migration by converting the 2S battery voltage to 1S-equivalent output and allows designers to preserve the existing downstream 1S power architecture.

The inductorless switched-capacitor converter topology of the IC shrinks the overall footprint and reduces the maximum height of the circuit. Its high switching frequency, up to 1.5MHz, reduces the size and number of capacitors required, further minimizing the solution footprint. The IC ensures safe operation with integrated overvoltage, undervoltage, overcurrent, and thermal protection, and also minimizes EMI with built-in frequency dithering. In addition to the small solution size, lower EMI, and protection features, the ICs class-leading peak efficiency of 98.5% simplifies thermal design and makes it ideal for consumer, medical, and industrial applications.

The IC features an I2C compatible, 2-wire serial interface consisting of a bidirectional serial data line (SDA) and a serial clock line (SCL). The IC supports SCL clock rates up to 3.4MHz. The converter parameters such as OCP, OVLO or UVLO thresholds, switching frequency, soft-start current, and duration are easily adjustable through the I2C interface. The IC consumes a low quiescent current of 30μA when operating and 4μA in shutdown. The IC is available in a tiny, lead-free 0.4mm pitch, 2.4mm x 2.8mm 42-pin wafer-level package (WLP).
