DESCRIPTION

The DCP01B series is a family of 1W, unregulated, isolated DC/DC converters. Requiring a minimum of external components and including on-chip device protection, the DCP01B series provides extra features such as output disable and synchronization of switch- ing frequencies. The use of a highly integrated package design results in highly reliable products with a power density of 40W/in 3 (2.4W/cm3). This combination of features and small size makes the DCP01B suitable for a wide range of applications.

Basic Model Number: 1W Product Voltage Input: 5V In Voltage Output: 5V Out Dual Output: Model Revision: Package Code: P = PDIP-14 P-U = PDIP-14 Gull-Wing ELECTROSTATIC DISCHARGE SENSITIVITY This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degrada- tion to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
