Description
General part information
ISL78208 Series
The ISL78208 is a dual standard buck regulator capable of 3A per channel with continuous output current. With an input range of 4. 5V to 28V, it provides a high frequency power solution for a variety of point of load applications. The PWM controller in the ISL78208 drives an internal switching N-Channel power MOSFET and requires an external Schottky diode to generate the output voltage. The integrated power switch is optimized for excellent thermal performance up to 3A of output current. The PWM regulator switches at a default frequency of 500kHz and it can be user programmed or synchronized from 300kHz to 2MHz. The ISL78208 utilizes peak current mode control to provide flexibility in component selection and minimize solution size. The protection features include overcurrent, UVLO and thermal overload protection. The ISL78208 is available in 5mmx5mm 32 Ld Wettable Flank Quad Flat Pb-free (WFQFN) package. The ISL78208 is rated for the automotive temperature range (-40°C to +105°C).
