Hot-selling and scarce IRU3037CSTRPBF 8-PIN SYNCHRONOUS PWM CONTROLLER spot stock

Product Descriptions

.The IRU3037 controller IC is designed to provide a lowcost synchronous Buck regulator for on-board DC to DCconverter applications.With the migration of today’s ASICproducts requiring low supply voltages such as 1.8V andlower,together with currents in excess of 3A,traditionallinear regulators are simply too lossy to be used wheninput supply is 5V or even in some cases with 3.3Vinput supply.The IRU3037 together with dual N-channelMOSFETs such as IRF7313,provide a low cost solutionfor such applications . This device features an internal200KHz oscillator (400KHz for "A"version),under-voltage lockout for both Vcc and Vc supplies, an externalprogrammable soft-start function as well as output under-voltage detection that latches off the device when anoutput short is detected .
