CS5173EDR8G

Product Summary

CS5173EDR8G is a 1.5A, 560 kHz switching regulator with a high efficiency. The CS5173EDR8G operates over a wide input voltage range, from 2.7V to 30V. The flexibility of the design of the Boost Regulator allows the chips to operate in most power supply configurations, including boost, flyback, forward, inverting and SEPIC. The CS5173EDR8G utilizes current mode architecture, which allows excellent load and line regulation, as well as a practical means for limiting current. Combining high frequency operation with a highly integrated regulator circuit results in an extremely compact power supply solution. The CS5173EDR8G circuit design includes provisions for features such as frequency synchronization, shutdown, and feedback controls for either positive or negative voltage regulation.

Parametrics

CS5173EDR8G absoluting maximum ratings: (1) Junction Temperature Range: 40°C to +150°C; (2) Storage Temperature Range, TSTORAGE: 65°C to150°C; (3) Lead Temperature Soldering: Reflow (Note 1) : 230°C Peak; (4) ESD, Human Body Model: 1.2kV. Note: Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. 60 second maximum above 183°C.
