LTC7510

LTC7510 Digital DC/DC Controller with PMBus Interface FEATURES PMBusTM Serial Interface for Programming and Telemetry ■ Digital PID Control Loop ■ Output Voltage Range: 0.7V to V CC – 0.9V ■ Optional Resistor-Based PMBus Address, Output Voltage, Frequency and Current Limit Set ■ www.DataSheet4U.com 150kHz to 2MHz Switching Frequency ■ DCR Current Sense with Temperature Compensation ■ Adjustable Active Voltage Positioning (AVP) Control ■ On-Chip Non-Volatile Memory (NVM) for Configuration Storage ■ Soft-Start Into Pre-Biased Load ■ Current Sharing ■ 32-Lead (5mm × 5mm) QFN Package ■ 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. Power supply sequencing, margining, turnon/-off and fault detection are easily programmed via the PMBus interface. The LTC7510 uses a digital control loop which eliminates external compensation components. The controller supports current sharing of multiple ICs; up to four controllers can be synchronized for multiphase operation. 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. , LT , LTC and LTM are registered trademarks of Linear Technology Corporation. All other trademarks are the property...
