Design Note 373: LT3470 ThinSOT Micropower Buck Regulator Low Output Ripple Application Note
The document introduces the LT3470, a monolithic step-down DC/DC converter that integrates the high-side power switch, catch diode, and boost diode into a single ThinSOT package. This integration simplifies circuit design by eliminating external components typically required for high-voltage switching applications.
