The ISL98603 integrates a high power boost converter for AVDD generation, VON and VOFF charge pump drivers, one synchronous buck regulator, and one synchronous buck controller for 2 logic voltages. The VON slicing circuitry and power-good function are also included. Operating at 1.3MHz, the AVDD boost converter features a 5.0A boost FET. Feedback is taken from the far side of the delay FET for improving regulation. The OVP circuit protects output side components. 11/9/2011 ISL98603 5 Channel DC/DC Converter + V<sub>ON</sub> Slice + Power-Good The logic synchronous buck converter features two 2.3A FETs operating at 1.3MHz internal clock. The output voltage is set by the IC internally or feedback resistor. The soft-start circuitry are also integrated with the buck. The second logic voltage is generated from synchronous buck converter with MOSFET controllers. The overcurrent protection is also integrated with the buck. The charge pump of VON and VOFF use the full switching frequency and integrates the driver for high current capability. VON is further processed through an integrated VON Slice circuit in order to reduce flicker. Alternative fixed voltages at the boost, Buck1, Buck2, VON charge pump, and VOFF charge pump are available in ISL98603, please contact Intersil Marketing via email at Packaging / Samples / Ordering iBuy direct from Intersil Check distributor inventory Part No. ISL98603IRAAZ-T ISL98603IRAAZ-T7A ISL98603IRAAZ-TK iBuy direct - out of stock Available in RoHS/Pb-Free Design-In Status Active Active Active Active Temp.
