High Efficiency 24V Input, 12A Synchronous Buck Converter

SGM612A12.pdf

The SGM612A12 is a wide 4.5V to 24V input voltage, 0.6V to 5.5V output voltage, 12A continues output current, synchronous Buck converter with integrated power MOSFETs. This device uses constant on-time (COT) control topology to get fast transient response.

The SGM612A12 has four selectable switching frequencies 500kHz, 800kHz, 1MHz and 1.2MHz by FS pin. The device has adjustable cycle-by-cycle valley over-current protection by CLM pin to meet various applications.

The SGM612A12 has a MODE pin to select power saving mode (PSM) or ultrasonic mode (USM) during light loading. In PSM, it could get high light loading efficiency by skip pulse. In USM, it could avoid acoustic noise.

The SGM612A12 provides OV (over-voltage), UV (under-voltage), OT (over-temperature) and UVLO (under-voltage lockout) protections combined with power-good indicator and build-in output discharge function.

The SGM612A12 is available in a Green TQFN-3×4-19L package.
