DATASHEET  
ISL9440B, ISL9440C  
Triple Step-Down PWM and Single Linear Controller with Programmable Soft-Start  
FN6799  
Rev 4.00  
February 18, 2016  
The ISL9440B and ISL9440C are quad-output synchronous  
buck controllers that integrate three PWM controllers and one  
Features  
• Three Integrated Synchronous Buck PWM Controllers  
- Internal Bootstrap Diodes  
low drop-out linear regulator controller, which are full 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 0.8V. The PWMs are  
synchronized at 180° out-of-phase thus, reducing the RMS  
input current and ripple voltage.  
- Internal Compensation  
• Independent Control for each Regulator and  
Programmable Output Voltages; Independent  
Enable/Shutdown/Soft-start  
• Fixed Switching Frequency: 300kHz(B), 600kHz(C)  
The ISL9440B and ISL9440C offer programmable soft-start,  
independent enable inputs for ease of supply rail  
sequencing, and integrated UV/OV/OC/OT protections in a  
space conscious 5mmx5mm QFN package. An early  
warning function is offered to output a logic signal to warn  
the system to back up data when input voltage falls below a  
certain level.  
• Adaptive Shoot-Through Protection on all Synchronous  
Buck Controllers  
• Pre-biased Output Start-up Capability  
• Out-of-Phase Switching to Reduce Input Capacitance  
(0°/180°/0°)  
• No External Current Sense Resistor  
- Uses Lower MOSFET’s rDS(ON)  
The ISL9440B and ISL9440C utilize internal loop  
compensation to keep minimum peripheral components for  
compact design and a low total solution cost. These devices  
are implemented with current mode control with feed-forward  
to cover various applications even with fixed internal  
compensations.  
• Current Mode Controller with Voltage Feed-Forward  
• Complete Protection  
- Overcurrent, Overvoltage, Undervoltage Lockout,  
Over-Temperature

features.
