Maxim Integrated
General Description
The MAX17030/MAX17036 are 3/2-phase interleaved Quick-PWM™ step-down VID power-supply controllers for IMVP-6.5 notebook CPUs. Two integrated drivers and the option to drive a third phase using an external driver such as the MAX8791 allow for a flexible 3/2-phase configuration depending on the CPU being supported.
FEATUREs
♦ Triple/Dual-Phase Quick-PWM Controllers
♦ 2 Internal Drivers + 1 External Driver
♦ ±0.5% VOUT Accuracy Over Line, Load, and Temperature
♦ 7-Bit IMVP-6.5 DAC
♦ Dynamic Phase Selection Optimizes Active/Sleep Efficiency
♦ Transient Phase Overlap Reduces Output Capacitance
♦ Transient Suppression Feature (MAX17036 Only)
♦ Integrated Boost Switches
♦ Active Voltage Positioning with Adjustable Gain
♦ Accurate Lossless Current Balance and Current Limit
♦ Remote Output and Ground Sense
♦ Adjustable Output Slew-Rate Control
♦ Power-Good (IMVPOK), Clock Enable (CLKEN), and Thermal-Fault (VRHOT) Outputs
♦ IMVP-6.5 Power Sequencing and Timing Compliant
♦ Output Current Monitor (IMON)
♦ Drives Large Synchronous Rectifier FETs
♦ 7V to 26V Battery Input Range
♦ Adjustable Switching Frequency (600kHz max)
♦ Undervoltage, Overvoltage, and Thermal-Fault Protection
