ZXSC440 - DC-DC BOOST SWITCHING CONTROLLERS

Download the ZXSC440 datasheet PDF. This datasheet also covers the ZXSC410 variant, as both devices belong to the same dc-dc boost switching controllers family and are provided as variant models within a single manufacturer datasheet.

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.

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 reached the required current/voltage.
