TPS43336-Q1 Single-Boost Dual Synchronous-Buck Controller

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. The integrated boost controller allows the devices to operate down to 2 V at the.
