DATASHEET ISL8105B +5V or +12V Single-Phase Synchronous Buck Converter PWM Controller with Integrated MOSFET Gate Drivers, Extended Soft-Start Time FN6447 Rev 2.00 April 15, 2010 The ISL8105B 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 ISL8105B 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.
