New 3/2-phase interleaved Quick-PWM step-down VID controllers for IMVP-6.5 CPUs

Maxim has introduced the MAX17030/MAX17036, a 3/2-phase interleaved Quick-PWM step-down VID power-supply controllers supporting IMVP-6.5 notebook CPUs. Two integrated drivers support 2-phase standard voltage (SV) cores, while an optional external driver configuration supports 3-phase extreme edition (XE) cores. This unique feature provides high design flexibility for both IMVP-6.5 XE and SV cores.

The key features of the MAX17030/MAX17036 controllers are,

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) that reduces the soar/sag voltage.
Integrated boost switches
Accurate lossless current balance and current limit
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

The Quick-PWM control provides instantaneous response to fast load-current steps. Active voltage positioning reduces power dissipation and bulk output capacitance requirements and allows ideal positioning compensation for tantalum, polymer, or ceramic bulk output capacitors.

The MAX17030/MAX17036 are intended for bucking down the battery directly to create the core voltage. The single-stage conversion method allows this device to directly step down high-voltage batteries for the high possible efficiency.

Package: 5mm x 5mm, 40-pin TQFN package with an exposed backside pad
Operating temperature range: -40°C to +105°C
Price: Starts at $5.46 for 1k pieces
Availability: Now
