SP6121 Datasheet (Sipex) - Low Voltage / Synchronous Step Down PWM Controller

SP6121, Low Voltage / Synchronous Step Down PWM Controller

The SP6121 is a fixed frequency, voltage mode, synchronous PWM controller designed to work from a single 5V or 3.3V input supply, providing excellent AC and DC regulation for high efficiency power conversion.

The operating frequency is internally set at 500kHz, permitting the use of small, surface m
