The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table defines the conditions for actual device operation.(1)

Notes:
1. Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Absolute maximum ratings apply individually only, not in combination. Unless otherwise specified, all other voltages are referenced to AGND.

DescriptionThe FAN5099 combines a high-efficiency pulse-width modulated (PWM) controller and an LDO (Low DropOut) linear regulator controller. The PWM controller is designed to operate over a wide frequency range (50kHz to 600kHz) to accommodate a variety of applications. Synchronous rectification provides high efficiency over a wide range of load currents. Efficiency is further enhanced by using the low-side MOSFET?s RDS(ON) to sense current. In addition, the capability to operate at low switching frequencies provides opportunities to boost power supply efficiency by reducing switching losses and gain cost savings using low-cost materials, such as powdered iron cores, on the output inductor.
Both the linear and PWM regulator soft-start are controlled by a single external capacitor, to limit in rush current from the supply when the regulators are first enabled. Current limit for PWM is also programmable.
The FAN5099's ability to handle wide input voltage ranges makes this controller suitable for power solutions in a wide range of applications involving conversion input voltages from Silver box, battery, and adapters. The PWM regulator employs a summing-current-mode control with external compensation to achieve fast load transient response and provide system design optimization.
FAN5099 is offered in both industrial temperature grade (-40?C to +85?C) as well as commercial temperature grade (-10?C to +85?C).
