ISL6545 Szczegóły Produktu

The ISL6545 makes simple work out of implementing a
complete control and protection scheme for a DC/DC stepdown
converter driving N-Channel MOSFETs in a synchronous buck
topology. Since it can work with either 5V or 12V supplies, this
one IC can be used in a wide variety of applications within a
system. The ISL6545 integrates the control, gate drivers, output
adjustment, monitoring and protection functions into a single
8 Ld SOIC or 10 Ld DFN package.
The ISL6545 provides single feedback loop, voltage-mode
control with fast transient response. The output voltage can be
precisely regulated to as low as 0.6V, with a maximum
tolerance of ±1.0% over-temperature and line voltage
variations. A selectable fixed frequency oscillator (ISL6545 for
300kHz; ISL6545A for 600kHz) reduces design complexity,
while balancing typical application cost and efficiency.
The error amplifier features a 20MHz gain-bandwidth
product and 9V/µs slew rate which enables high converter
bandwidth for fast transient performance. The resulting
PWM duty cycles range from 0% to 100%.
Protection from overcurrent conditions is provided by
monitoring the rDS(ON) of the lower MOSFET to inhibit PWM
operation appropriately. This approach simplifies the
implementation and improves efficiency by eliminating the
need for a current sense resistor.
