HV-9120 - Supertex

HV-9120 HV9120

The Supertex HV9120 and HV9123 are Switch Mode Power Supply (SMPS) controller subsystems that can start and run directly from almost any DC input, from a 12V battery to a rectified and filtered 240V AC line. They contain all the elements required to build a single-switch converter except for the switch, magnetic assembly, output rectifier(s) and filter(s). A.

❏ ❏ ❏ ❏ ❏ 10 to 450V input acceptance range <1.3mA supply current >1.0MHz clock >20:1 dynamic range @ 500KHz Low internal noise General Description The Supertex HV9120 and HV9123 are Switch Mode Power Supply (SMPS) controller subsystems that can start and run directly from almost any DC input, from a 12V battery to a rectified and filtered 240V AC line. They contain all the elements required to build a single-switch converter except for the switch, magnetic assembly, output rectifier(s) and filter(s). A unique input circuit allows the 912x to self-start directly from a high voltage input, and.
