ISL9443规格书详情
The ISL9443 is a triple-output synchronous buck controller that
integrates three PWM controllers which are fully featured and
designed to provide multi-rail power for use in products such as
cable and satellite set-top boxes, VoIP gateways, cable modems,
and other home connectivity products as well as a variety of
industrial and general purpose applications. Each output is
adjustable down to 0.7V. The PWMs are synchronized at 180°
out-of-phase, thus reducing the input RMS current and ripple
voltage.
The ISL9443 offers programmable soft-start and tracking
functions for ease of supply rail sequencing and integrated
UV/OV/OC/OT protections in a space conscious 5mmx5mm QFN
package.
Switching frequency can be set between 200kHz and 1200kHz
using a resistor. The ISL9443 can be synchronized to an external
clock to reduce beat frequencies.
The ISL9443 utilizes internal loop compensation to keep
minimum peripheral components for a compact design and a
low total solution cost. The controller is implemented with
current mode control with feed forward to cover various
applications even with fixed internal compensation.
