ISL6415
Triple Output Regulator with Single Synchronous Buck and Dual LDO
FN9145 Rev 0.00 Dec 27, 2004
The ISL6415 is a highly integrated triple output regulator which provides a single chip solution for wireless chipset power management. The device integrates a high efficiency synchronous buck regulator with two ultra low noise LDO regulators. The IC accepts an input voltage range of 3.0V to 3.6V and provides three regulated output voltages: 1.2V (PWM), 1.8V (LDO1), and another ultra-clean 1.8V (LDO2).
The Synchronous current mode PWM regulator with integrated N- and P- channel power MOSFET provides preset 1.2V for BBP/MAC core supply. Synchronous rectification with internal MOSFETs is used to achieve higher efficiency and reduced number of external components.
