DESCRIPTION
The ZSPM4023-06 operates at a constant 600kHz (typical) switching frequency in continuousconduction mode and can be used to provide up to 6A of output current. The output voltage is adjustable from 5.5V down to 0.8V. Under medium to heavy loads, the ZSPM4023-06 provides high efficiency and ultra-fast transient response via its rapid-control architecture. Under light load conditions, it maintains high efficiency and a superior transient response by transitioning to variable-frequency, discontinuous mode operation with its ultra-light-load architecture. The ZSPM4023-06 offers a full suite of protection features to ensure protection of the IC during fault conditions. These include under-voltage lockout to ensure proper operation under power-sag conditions; thermal shutdown; internal soft-start to reduce inrush current; foldback current limiting; and “hiccup” mode short-circuit protection. The ZSPM4023-06 includes a power good (PG) output to allow simple sequencing. ZSPM4023-06...
