The NCP1271D65R2G from On Semiconductor is a fixed-frequency, current-mode PWM controller with ramp compensation and skip cycle capabilities in standby conditions. It is designed for applications requiring ruggedness and component cost efficiency, such as AC-DC adapters for notebooks and LCD monitors, offline battery chargers, and consumer electronics like STBs and DVD players.
This controller utilizes a proprietary "Soft-Skip Mode" technique for optimal noise control in standby, reducing acoustic noise and allowing the use of less expensive clamping network components. It also features internal frequency jittering for a softened EMI signature, timer-based fault protection for improved overload detection, and an internal latch for easy implementation of overvoltage and overtemperature protection.
The NCP1271D65R2G operates with a switching frequency of 65kHz and supports a wide input voltage range of 10V to 20V. It offers a maximum output current of 800mA and a duty cycle of up to 80%. The device is housed in a 7-SOIC surface-mount package and operates within an ambient temperature range of -40°C to 125°C.
Key features include adjustable skip level, internal high-voltage startup current source for lossless startup, and pin-to-pin compatibility with the existing NCP120X series. It is Pb-Free and Halogen-Free compliant.
