Product details
Overview
ADP3206JCPZ-REEL from Analog Devices is a 2-/3-/4-phase synchronous buck controller optimized for IMVP-5-compliant Intel® CPU core power delivery. It features a 6-bit VID DAC (0.8375 V–1.6 V output), ±10 mV regulation accuracy over temperature, logic-level PWM outputs, and active per-phase current/thermal balancing. It targets notebook/desktop VRMs requiring dynamic voltage scaling and tight load-line control.
For engineers reviewing the ADP3206JCPZ-REEL datasheet, ADP3206JCPZ-REEL pinout, ADP3206JCPZ-REEL application, or ADP3206JCPZ-REEL equivalent, key selection criteria include IMVP-5 VID decoding fidelity, programmable phase count (2/3/4), deep/deeper sleep offset programming, soft transient slew control, and integrated current-sense amplifier with CSSUM/CSCOMP architecture.
Technical Context
The ADP3206JCPZ-REEL implements a multimode fixed-frequency PWM architecture with internal 6-bit VID DAC compliant to Intel IMVP-5 specifications. Its oscillator frequency (0.25–4 MHz master clock) is set via external RT resistor and divided by active phase count (2/3/4) to determine per-phase switching frequency up to 1 MHz.
It uses differential remote sensing (FB/FBRTN), dedicated current-sense amplifier (CSREF/CSSUM/CSCOMP), and independent per-phase SWx inputs for thermal-current balancing. Phase enable/disable is determined by grounding PWM3/PWM4 pins during startup detection, with internal comparators verifying <300 mV threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VID DAC Range | 0.8375 V to 1.6 V - sets core voltage per IMVP-5 processor command; 6-bit resolution enables 12.5 mV steps. |
| Regulation Accuracy | ±10 mV over 0°C–100°C - ensures stable CPU operation under thermal stress without external calibration. |
| Phase Configuration | 2-, 3-, or 4-phase selectable via PWM3/PWM4 pin grounding - enables scalable VRM design from low-cost dual-phase to high-current quad-phase. |
| Current Sense Interface | CSSUM/CSCOMP/CSREF pins - supports ESR-based or resistor-based inductor current summation for accurate load-line positioning. |
| Soft Transient Control | STSET pin with capacitor - programmable slew rate limits inrush during VID transitions, preventing overshoot/undershoot. |
| Thermal Throttling | TTSENSE/VRTT/TTMASK pins - monitors remote hot-spot temperature and asserts logic signal to CPU when threshold exceeded. |
| Package | 40-lead LFCSP (6 mm × 6 mm, 0.5 mm pitch) - thermally enhanced leadframe chip-scale package for high-power density VRM layouts. |
Pinout & Package
ADP3206JCPZ-REEL is housed in a 40-lead LFCSP (Lead Frame Chip Scale Package) with exposed thermal pad, optimized for thermal dissipation in compact VRM designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VID0–VID5 | Voltage ID Inputs | 6-bit bus read directly by internal DAC; open-circuit = logic high; all open = "No CPU" shutdown mode. |
| PWM1–PWM4 | Logic-Level PWM Outputs | Drive external gate drivers (e.g., ADP3419); grounding PWM3/PWM4 disables corresponding phases. |
| SW1–SW4 | Per-Phase Current Sense Inputs | Connect to switch-node side of each inductor; enable active current/thermal balancing across phases. |
| CSSUM / CSCOMP / CSREF | Current Sense Amplifier Interface | CSSUM sums phase currents; CSREF is reference node; CSCOMP sets gain/slope for load-line positioning. |
| DPSLP / DPRSLP / DPSET / STSET | Sleep Mode Control Inputs | Program deep/deeper sleep offsets, transient slew, and reference voltages for low-power CPU states. |
| RT / RAMPADJ / ILIMIT / DELAY | Programmable Timing/Protection Nodes | RT sets master clock; RAMPADJ adjusts PWM ramp slope; ILIMIT sets current limit threshold; DELAY configures soft-start/latch-off delay. |
Key Features
| Feature | Design Value |
|---|---|
| IMVP-5 VID Compliance | Fully implements Intel's 6-bit VID protocol with ±10 mV accuracy, enabling direct interface to Pentium M/Core Duo processors without external DAC. |
| Active Per-Phase Balancing | Independent SWx inputs + internal balancing circuit ensure initial current match ≤5% and dynamic thermal redistribution during load transients. |
| Programmable Load-Line Positioning | CSCOMP feedback resistor sets droop impedance; combined with CSSUM current summing, achieves precise voltage positioning vs. load current. |
| On-the-Fly VID Transition Support | Built-in PWRGD blanking and crowbar masking (via PGMASK capacitor) prevent false power-good faults during CPU-requested voltage changes. |
| Integrated Thermal Throttling | TTSENSE input monitors remote VR hotspot; VRTT output signals CPU within 90 µs of threshold breach, enabling immediate frequency throttling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiphase buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6322IRZ | 6-phase capable; integrates MOSFET drivers; no external RAMPADJ adjustment; ±15 mV VID accuracy. | Targets higher-current server CPUs; requires driver-integrated layout; less flexible ramp tuning than ADP3206JCPZ-REEL. | Choose ISL6322IRZ when board space is constrained and integrated drivers reduce BOM count; avoid if discrete driver selection or fine ramp control is required. |
| TPS51216RGER | 3-phase only; supports IMVP-6.5; includes integrated 5-V LDO; ±8 mV accuracy; smaller 20-pin QFN package. | Designed for newer Intel Core i-series; lacks deeper sleep control and TTSENSE thermal monitoring capability. | Choose TPS51216RGER for cost-sensitive mobile designs requiring IMVP-6.5 compliance; retain ADP3206JCPZ-REEL for IMVP-5 legacy platforms with thermal throttling needs. |
Compared with ISL6322IRZ and TPS51216RGER, ADP3206JCPZ-REEL offers unique support for IMVP-5-specific deep/deeper sleep modes, independent RAMPADJ-based PWM slope tuning, and dedicated TTSENSE/VRTT thermal signaling-making it irreplaceable for validated Pentium M/Core Duo VRM designs requiring full specification compliance.

FAQ
What is the operating temperature range for the ADP3206JCPZ-REEL?
The ADP3206JCPZ-REEL is specified for commercial operation from 0°C to +100°C ambient temperature. Its internal circuitry-including the VID DAC, error amplifier, and current sense amplifier-is characterized and guaranteed to meet all electrical specifications across this full range, including ±10 mV output accuracy and stable phase-balancing performance.
How does the ADP3206JCPZ-REEL support IMVP-5 deep and deeper sleep modes?
The ADP3206JCPZ-REEL supports IMVP-5 deep sleep via DPSLP and DPSET pins, which program an offset voltage applied during low-power states, and deeper sleep via DPRSLP and DPRSET pins, which reconfigure the DAC reference to achieve lower standby voltages. These functions are implemented with dedicated internal amplifiers and are verified per IMVP-5 timing and accuracy requirements.
Can the ADP3206JCPZ-REEL be configured for 2-phase operation, and how is it done?
Yes, the ADP3206JCPZ-REEL can be configured for 2-phase operation by grounding both PWM3 and PWM4 pins during power-up. The device detects these low states within the first two oscillator cycles and disables the corresponding phases, leaving only PWM1 and PWM2 active. External pull-down resistors must exceed 25 kΩ to ensure reliable detection.
What is the purpose of the RAMPADJ pin on the ADP3206JCPZ-REEL?
The RAMPADJ pin on the ADP3206JCPZ-REEL sets the slope of the internal PWM ramp by connecting an external resistor from the converter input voltage to this pin. This allows designers to optimize transient response and stability margins independently of switching frequency, a key advantage over fixed-ramp controllers in high-dV/dt CPU load scenarios.
Does the ADP3206JCPZ-REEL include short-circuit protection, and how is it configured?
Yes, the ADP3206JCPZ-REEL includes programmable short-circuit protection using the ILIMIT pin. An external resistor from ILIMIT to GND sets the current limit threshold (e.g., 120 mV typical for 4-phase operation), and the DELAY pin configures the latch-off delay time (1.2 ms typical with 250 kΩ/4.7 nF). Protection triggers crowbar action and holds PWM outputs low until reset via SD pin.
