The NCP1200 family is intended for consumer electronics and computing peripherals that operate from 5W to more than 100W. Both ICs offer a user-programmable peak current, output drive capability of 250mA, as well as a "skip-cycle" mode for improved efficiency at light loads.
The NCP1200A is a second-generation version of the existing NCP1200 but features an improved FET drive capability, lower standby power consumption, and the company's proprietary Dynamic Self-Supply circuitry that allows power to be drawn directly from a high-voltage rail at start-up, eliminating the need for an auxiliary transformer winding.
Both the NCP1203 and the NCP1200 are offered in a surface-mount SO-8 package as well as the traditional PDIP-8 package. |
