This datasheet also covers the LM5156 variant, as both devices belong to the same non-synchronous boost/sepic/flyback controller family and are provided as variant models within a single manufacturer datasheet.
General Description
The LM5156x (LM5156 and LM51561) device is a wide input range, non-synchronous boost controller that uses peak current mode control.
The device can be used in boost, SEPIC, and flyback topologies.
Key Features
Functional Safety-Capable.
Documentation available to aid functional safety system design.
