ISL8510
FN6516.2
Dual Output Controller with 1A Standard
Buck PWM and LDO
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. The enable pin
(EN_LDO) controls the 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 Regulator Capacitor Selection”
on page 16.
The ISL8510 is available in a small 4mmx4mm Quad Flat No
Lead (QFN) package.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTES:
1. An accidental short between VCC and GND may cause excessive heating and permanent damage to the device.
2. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See
Tech Brief TB379 for details.
3. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
