Quick-PWM VID Power Supply Controllers support IMVP-6.5 CPUs.
Press Release Summary:
Supplied in 5 x 5 mm package, step-down VID power-supply controllers MAX17030/MAX17036 have 2 integrated drivers that support 2-phase standard voltage cores and optional external driver configuration that supports 3-phase extreme edition cores. Three phases operate 120° out-of-phase, minimizing I/O filter requirements and EMI. Current-sense resistors and low-offset amps maintain current balance across 3 phases, reducing instantaneous input current of each phase and input-voltage ripple.
Original Press Release:
3-/2-phase, Quick-PWM(TM) VID Controllers for IMVP-6.5 CPUs
SUNNYVALE, CA-October 15, 2009-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX17030/MAX17036, 3/2-phase, interleaved, 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 greater design flexibility by allowing the MAX17030/MAX17036 to be used for both IMVP-6.5 XE and SV cores.
The three phases operate 120° out-of-phase to minimize input/output filter requirements, improve efficiency, and reduce EMI. Current-sense resistors and low-offset amplifiers maintain current balance across the three phases. By sharing the current across three phases, the devices reduce the instantaneous input current of each phase and, thus, the input-voltage ripple. The MAX17036 includes an additional transient-suppression feature that reduces the soar/sag voltage.
The MAX17030/MAX17036 are available in a space-saving, 5mm x 5mm, 40-pin TQFN package with an exposed backside pad. They are fully specified over the -40°C to +105°C temperature range. Prices start at $5.46 (1000-up, FOB USA). An evaluation kit with recommended external components is available to reduce design time.
