Boost converter with a 3.6A switch — output power anchor
Its integrated 3.6 A switch sets the output power ceiling — at a typical 5 V output, the available load current is limited by the switch current rating and input voltage, not the controller. The 600 kHz fixed switching frequency allows a small inductor and ceramic capacitors while keeping switching losses manageable for most portable and industrial rails.
Package and thermal: the 16-HTSSOP exposed pad
Synchronous rectification and adjustable output
The device includes a synchronous rectifier, which improves efficiency at moderate to heavy loads by replacing the external Schottky diode with an internal low-side FET.
