Description
The ISL8510 is a high-performance, dual output controller that provides a single, high frequency power solution for a variety of point of load applications. The ISL8510 integrates a 1A standard buck PWM controller and switching MOSFET with one 500mA LDO.
The PWM controller in the ISL8510 drives an internal switching N-Channel power MOSFET and requires an external Schottky diode to generate an output voltage from 0.6V to 20V. The integrated power switch is optimized for excellent thermal performance up to 1A of output current. The standard buck input voltage range supports a fixed 5V or variable 5.5V to 25V range. The PWM regulator switches at a fixed frequency of 500kHz and utilizes simple voltage mode control with input voltage feed forward to provide flexibility in component selection and minimize solution size. Protection features include overcurrent, undervoltage, and thermal overload protection integrated into the IC. The ISL8510 power good signal output indicates loss of regulation on the PWM output.
The ISL8510 features one adjustable LDO regulator using internal PMOS transistors as pass devices. Enable pin (EN_LDO) control LDO output. A single power good signal output indicates loss of regulation on the LDO output. Independent overcurrent and thermal fault shutdown monitors are integrated into the LDO section.
ISL8510 is available in a small 4mmx4mm Quad Flat No-Lead (QFN) package.
