Description
The SP6121CN-TR 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 mount inductors and capacitors. With its low voltage capability and inherent 100% duty cycle operation, the SP6121CN-TR allows low dropout operation in the event of a low input supply voltage condition.
