LTC7510  
Digital DC/DC Controller  
with PMBus Interface  
FEATURES  
DESCRIPTION  
The LTC®7510 is a digital DC/DC controller with onboard  
non-volatile memory and PMBus interface for real time  
reporting and control of point-of-load (POL) power  
management. Powersupplysequencing, margining, turn-  
on/-off and fault detection are easily programmed via the  
PMBus interface.

■
Voltage, Frequency and Current Limit Set  
150kHz to 2MHz Switching Frequency  
■
The LTC7510 uses a digital control loop which eliminates  
external compensation components. The controller sup-  
portscurrentsharingofmultipleICs;uptofourcontrollers  
can be synchronized for multiphase operation.  
■
DCR Current Sense with Temperature Compensation  
■
Adjustable Active Voltage Positioning (AVP) Control  
■
On-Chip Non-Volatile Memory (NVM) for  
Configuration Storage  
■
The LTC7510 provides superior accuracy through  
internal calibration to correct current sense error  
sources upon start-up and programmable temperature  
compensation provides accurate current sensing over  
temperature. The LTC7510 is available in a 32-lead (5mm  
× 5mm) QFN package.
