A precise 5-bit digital to analog converter (DAC) allows adjusting the output voltage from 0.800V to 1.550V with 25mV binary steps managing On-The-Fly VID code changes.
The high precision internal reference assures the selected output voltage to be within ±0.6%. The high peak Current gate drive affords to have fast switching to the external power mos proVIDing low switching losses.
The device assures a fast protection against Load over Current and Load over/under voltage. An internal crowbar is proVIDed turning on the low side mosfet if an over-voltage is detected. In case of over-Current, the system works in Constant Current mode.

Description : 2-Phase, 5-Bit VID, Current Mode, High Efficiency, Synchronous Step-Down Switching Regulators

DESCRIPTION
The LTC®1709-8/LTC1709-9 are 2-phase, VID Programmable, synchronous step-down switching regulator controllers that drive two all N-channel external power MOSFET stages in a fixed frequency architecture. The 2-phase controller drives its two output stages out of phase at frequencies from 150kHz to 300kHz to minimize the RMS ripple Currents in both input and output capacitors. The 2- phase technique effectively multiplies the fundamental frequency by two, improving transient response while operating each channel at an optimum frequency for efficiency. Thermal design is also simplified.

FEATURES
■ Single Controller Operates Two Output Stages Antiphase Reducing Required Input Capacitance and Power Supply Induced Noise
■ Two 5-Bit Desktop VID Codes:
    LTC1709-8 for VRM8.4 (VOUT from 1.3V to 3.5V)
    LTC1709-9 for VRM9.0 (VOUT from 1.1V to 1.85V)
Current Mode Control Ensures Best Current Sharing
■ True Remote Sensing Differential Amplifier
■ Power Good Output Indicator
■ OPTI-LOOPTM Compensation Minimizes COUT
Programmable Fixed Frequency: 150kHz to 300kHz
■ ±1% Output Voltage Accuracy
■ Wide VIN Range: 4V to 36V Operation
■ Adjustable Soft-Start Current Ramping
■ Internal Current Foldback and Short-Circuit Shutdown
