MAX25431ATGA/VY+

The MAX25431ATGA/VY+ is a current-mode buck-boost controller. The device operates with input voltages from 6V to 36V. The switching frequency is resistor programmable from 220KHz to 2.2MHz and can be synchronized to an external clock. The device output voltage is available as 5V fixed or adjustable from 4V to 25V. The wide input voltage range, along with its ability to maintain constant output voltage during battery transients, makes the device ideal for automotive applications. In light load applications, a logic input (FSYNC) allows the devices to operate in fixed-frequency, forced-PWM mode to eliminate frequency variation and help minimize EMI. Protection features include cycle-by-cycle current limit followed by hiccup during sustained overloads, input under-voltage lockout (UVLO), out- put overvoltage protection and thermal shut- down with automatic recovery.

• Meets stringent automotive quality and reliability requirements
• Small 4mm x 4mm 24pin SWTQFN package
• 10µA (max) quiescent current in shutdown
• EMI mitigation to meet CISPR25 Class 5 requirements
