ZXSC410/ZXSC420/ZXSC440
DC-DC BOOST SWITCHING CONTROLLERS
Description
The ZXSC410/420/440 are DC-DC boost controllers.
Their wide input voltage range makes them suitable for operation for a number of battery configurations including single Li-Ion cell and 2~3 alkaline/NiCd/NiMH cells.
Using high gain Diodes Zetex-brand switching
npn-
transistors allows high-voltage boost ratios and/or high output current depending on the
transistor.
The ZXSC410/440 has a shutdown feature that can also be used for some dimming functionality.
ZXSC420/440 includes an End of Regulation flag that can be used to indicate when the
regulator is no longer able to maintain the regulated output voltage/current or has r...
