Rev. 2 (277.0kB)
Product Overview
»View Material Composition
» Product Change Notification
The NCP3126 is a flexible synchronous PWM Switching Buck Regulator. The NCP3126 is capable of producing output voltages as low as 0.8 V. The NCP3126 also incorporates voltage mode control. To reduce the number of external components, a number of features are internally set, including soft-start and switching frequency. The NCP3126 is currently available in an SOIC-8 package. Family of parts that are pin to pin compatible. NCP3125 (4A), NCP3126 (3A), NCP3127 (2A)
