DATASHEET ISL8560MR FN6621 Rev 1.00 DC/DC Power Switching Regulator November 11, 2011 The ISL8560MREP is a step down DC/DC power switching Features regulator which accepts 9.0V to 60V input and provides a 2A Specifications per DLA VID V62/08608 output current. The output voltage can be set in the range Full Mil-Temp Electrical Performance from -55C to +125C between 1.21V and 55V by means of an external divider. The device uses an internal power DMOS transistor with a Controlled Baseline with One Wafer Fabrication Site and typical r of 0.19 to obtain very high efficiency and One Assembly/Test Site DS(ON) high switching speed. A switching frequency in the range of Full Homogeneous Lot Processing in Wafer Fab 100kHz to 600kHz can be realized (the maximum power No Combination of Wafer Fabrication Lots in Assembly dissipation of the various packages must be observed). Full Traceability Through Assembly and Test by Notable features of this next generation of DC/DC converter Date/Trace Code Assignment includes pulse-by-pulse current limit for FET protection, hiccup mode for short circuit protection, voltage feedforward Enhanced Process Change Notification regulation, Frequency SYNC, soft-start, low standby current Enhanced Obsolescence Management of 60A typical in the disabled state, and thermal shut-down. Eliminates Need for Up-Screening a COTS Component The device is available in a 20 Ld QFN package. Voltage Feedforward Mode Device Information Step Down DC/DC Supporting up to 2A Based on Max T J The specifications for an Enhanced Product (EP) device are and VIN/VOUT defined in a Vendor Item Drawing (VID), which is controlled Input Voltage Range of 9.0V to 60V by the Defense Logistics Agency (DLA).
