Triple Output Regulator with Single Synchronous Buck and Dual LDO
FN9129 Rev 0.00 Oct 29, 2003
The ISL6413 is a highly integrated triple output regulator which provides a single chip solution for wireless chipset power management. The device integrates 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: 1.8V (PWM), 2.84V (LDO1), and another ultra-clean 2.84V (LDO2).
The Synchronous current mode PWM regulator with integrated N- and P-channel power
MOSFET provides preset 1.8V for BBP/MAC core supply. Synchronous rectification with internal
MOSFETs is used to achieve higher efficiency and reduced number of external components. Operating frequency is typically 750kHz allowing the use of smaller inductor and capacitor values. The device can be synchronized to an external clock signal in the range of 500kHz to 1MHz. The PG_PWM output indicat...
