ISL8105, ISL8105A
+5V or +12V Single-Phase Synchronous Buck Converter PWM Controller with Integrated MOSFET Gate Drivers
FN6306 Rev 5.00 April 15, 2010
The ISL8105, ISL8105A is a simple single-phase PWM controller for a synchronous buck converter. It operates from +5V or +12V bias supply voltage. With integrated linear regulator, boot diode, and N-Channel MOSFET gate drivers, the ISL8105, ISL8105A reduces external component count and board space requirements. These make the IC suitable for a wide range of applications.
Utilizing voltage-mode control, the output voltage can be precisely regulated to as low as 0.6V. The 0.6V internal reference features a maximum tolerance of ±1.0% over the commercial temperature range, and ±1.5% over the industrial temperature range.
