S6BP20x One-channel Buck-Boost DC/DC Converters

Cypress’s S6BP20x series (S6BP201A, S6BP202A, and S6BP203A) PMICs are automotive grade, one-channel buck-boost DC/DC converters for automotive and industrial applications. They are ideal for automotive applications such as Body Control modules, Instrument Clusters, and ADAS. These PMICs have low standby current, and provide stable power output across a wide range of input voltages.

Cypress's unique buck-boost technology enables a smaller PMIC system design by eliminating bulky expensive electrolytic capacitors for input filtering. This smaller design enables you to create a small, affordable and efficient power management solution.

The S6BP20x series is versatile and easy-to-integrate into new or existing automotive systems. Cypress’s Easy DesignSim™ web-based simulation and verification tool accelerates circuit development by easing iteration cycles.
