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
