Wide V IN Dual Standard Buck Regulator With 3A/3A
Continuous Output Current
ISL85033
The ISL85033 is a dual standard buck regulator capable of 3A
per channel 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 ISL85033 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 ISL85033 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 ISL85033 is available in a small 4mmx4mm Thin Quad
Flat Pb-free (TQFN) package.
