ISL88550A Description
DATASHEET ISL88550A Synchronous Step-Down Controller with Sourcing and Sinking LDO Regulator FN6168 Rev 3.00 April 23, 2008 ISL88550A integrates a synchronous buck PWM controller to generate VDDQ, a sourcing and sinking LDO linear regulator to generate VTT, and a 10mA reference output buffer to generate VTTR. The buck controller drives two external N-Channel MOSFETs to generate output voltages down to 0.7V from a 2V...
