The MIC26903YJL-TR is a constant-frequency, synchronous DC/DC buck regulator from Microchip Technology, featuring an adaptive on-time control architecture. It operates over a wide supply range of 4.5V to 28V and can provide up to 9A of output current. The output voltage is adjustable from 0.8V to 5.5V, with ±1% feedback accuracy.
This regulator utilizes Micrel's Hyper Light Load™ architecture, which maintains high efficiency under light load conditions by transitioning to variable frequency, discontinuous mode operation. It also offers Hyper Speed Control™ architecture for high-efficiency and ultra-fast transient response under medium to heavy loads. The device operates at a constant 600kHz switching frequency.
Key protection features include undervoltage lockout, thermal shutdown, internal soft-start, foldback current limit, and "hiccup mode" short-circuit protection. It includes a Power Good (PG) output for sequencing. The MIC26903YJL-TR is housed in a compact 5mm x 6mm MLF® (MicroLeadFrame) package, suitable for surface mounting.
Applications for this regulator include distributed power systems, telecom/networking infrastructure, and graphics cards.
