+5V or +12V Single-Phase Synchronous
Buck Converter PWM Controller with
Integrated MOSFET Gate Drivers
The ISL8105 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 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 鹵1.0% over the
commercial temperature range, and 鹵1.5% over the
industrial temperature range. Two fixed oscillator frequency
versions are available; 300kHz (ISL8105 for high efficiency
applications) and 600kHz (ISL8105A for fast transient
applications).
The ISL8105 features the capability of safe start-up with
pre-biased load. It also provides overcurrent protection by
monitoring the on resistance of the bottom-side MOSFET to
inhibit PWM operation appropriately. During start-up interval,
the resistor connected to BGATE/BSOC pin is employed to
program overcurrent protection condition. This approach
simplifies the implementation and does not deteriorate
converter efficiency.
