Product Summary
The CRCW080510K0JNEA is a high-speed synchronous buck regulator controller with a feedback voltage accuracy of ±1%. The CRCW080510K0JNEA can provide simple down conversion to output voltages as low as 0.6V. Though the control section of the IC is rated for 3 to 6V, the CRCW080510K0JNEA is designed to accept input supply rails as high as 14V. Applications are (1)dowconversiofrom 3.3v; (2)cable modem, dsl and adsl; (3)laser jet and ink jet printers; (4)low voltage power modules; (5)DSP, ASIC, Core and I/O.
