Product Details

The MAX16932/MAX16933 offer two high-voltage, synchronous step-down controllers that use only 20µA of quiescent current with no load. They operate with an input voltage supply from 3.5V to 42V and can operate in drop-out condition by running at 95% duty cycle. The devices are intended for applications with mid- to high-power requirements and requiring two independently controlled output supplies, such as automotive applications.

The MAX16932/MAX16933 step-down controllers operate 180° out-of-phase for reduced input ripple. The devices also operate with switching frequencies up to 2.2MHz to allow use of small external components and to guarantee no AM band interference. The FSYNC input programmability enables three frequency modes for optimized performance: forced fixed-frequency operation, skip mode with ultra-low quiescent current (20µA), and synchronization to an external clock. The devices provide a spread-spectrum option to minimize EMI interference.

The devices also feature a power-OK monitor and overvoltage and undervoltage lockout. Protection features include cycle-by-cycle current limit and thermal shutdown.

The devices are available in a 28-pin TQFN-EP package and are specified for operation over the -40°C to +125°C automotive temperature range.
