TPS43335-Q1 - Single-Boost Dual Synchronous-Buck Controller

General Description

The TPS43335-Q1 and TPS43336-Q1 include two current-mode synchronous buck controllers and a voltage-mode boost controller.

The devices are ideally suited as a pre-regulator stage with low Iq requirements and for applications that must survive supply drops due to cranking events.
