 2017-10-25

【产品特性】

Power system:
Input voltage — 3V to 28V
Integrated bootstrap switch
Programmable LDO output — 200mA
1% reference tolerance -40 to +85 °C
Selectable internal/external bias power supply
EcoSpeedTM architecture with pseudo-fixed frequency adaptive on-time control
The SC417/SC427 supports using standard capacitor types such as electrolytic or special polymer, in addition to ceramic, at switching frequencies up to 1MHz. The programmable frequency, synchronous operation, and selectable power-save provide high efficiency operation over a wide load range. In power-save mode, the minimum operating frequency for the SC417 is 25kHz whereas the SC427 has no minimum.

【产品应用】

Office automation and computing
Networking and telecommunication equipment
Point-of-load power supplies and module replacement.
