MIC24052YJL-TR More Semiconductors - ICs by Microchip Technology
19V/6A Buck Regulator with HyperLight Load®
| Status: | Active |
|---|---|
| Series: | MIC24052 |
| RoHS: | Compliant |
The MIC24052 is a constant-frequency, synchronous DC/DC buck regulator featuring adaptive on-time control architecture. The MIC24052 operates over a supply range of 4.5V to 19V. It has an internal linear regulator which provides a regulated 5V to power the internal control circuitry. The MIC24052 operates at a constant 600kHz switching frequency in continuous-conduction mode and can be used to provide up to 6A of output current. The output voltage is adjustable down to 0.8V.
HyperLight Load® architecture provides the same high-efficiency and ultra-fast transient response as the Hyper Speed Control™ architecture under medium to heavy loads, but also maintains high efficiency under light load conditions by transitioning to variable-frequency, discontinuous-mode operation.
The MIC24052 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 the inrush current, foldback current limit and "hiccup mode" short-circuit protection. The MIC24052 includes a power good (PG) output to allow simple sequencing.
