SP6122 Datasheet (Sipex) - Low Voltage Buck Controller

SP6122, Low Voltage Buck Controller

The SP6122 is a PWM/PFM minimum on-time controller designed to work from a single 3V5.5V input supply.

It is engineered specifically for size and minimum component count, simplifying the transition from a linear regulator to a switcher solution.

However, unlike other “micro” parts, the SP6122 has a
