Product details
Overview
MAX17000ETG+TG05 from Maxim Integrated is a complete DDR2/DDR3 memory power-management IC integrating a Quick-PWM™ step-down controller (VDDQ), ±2A source/sink LDO (VTT), and ±3mA reference buffer (VTTR) in a single 24-pin TQFN package. It delivers 1.5V or 1.8V VDDQ with 1% accuracy, supports 200–600kHz switching, and enables notebook memory rail sequencing with PGOOD1/PGOOD2 monitoring.
For engineers reviewing the MAX17000ETG+TG05 datasheet, MAX17000ETG+TG05 pinout, MAX17000ETG+TG05 application, or MAX17000ETG+TG05 equivalent, key selection criteria include VDDQ load-transient response (100ns), VTT deadband operation (±5mV), VTTR tracking accuracy (±20mV), thermal shutdown (160°C), and compatibility with DDR/DDR2/DDR3 SSTL-18 and SSTL-15 termination standards.
Technical Context
The MAX17000ETG+TG05 implements a constant-on-time Quick-PWM™ architecture for the VDDQ buck converter, enabling stable operation across wide VIN/VOUT ratios (3V–26V input, 1.0V–2.5V output) while maintaining fixed-frequency behavior and 100ns load-step response. Valley current sensing provides accurate overcurrent protection with 15–25mV threshold tolerance.
Its integrated VTT regulator operates in true source/sink mode with ±5mV deadband and ±2A peak capability, eliminating need for external discharge circuitry during memory standby. VTTR buffers either VCSL/2 or an external 0.5V–1.5V REFIN voltage, supporting flexible DDR bus reference generation with ±20mV accuracy at ±3mA load.
Key Specifications

Pinout & Package
MAX17000ETG+TG05 is housed in a 24-pin, 4mm × 4mm TQFN-EP package with exposed thermal pad connected to AGND. Pin functions are validated per Maxim's official datasheet Rev 2 (April 2013).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OVP | SMPS Overvoltage Control | Enables/disables SMPS OVP and internal discharge FETs; high (>2.4V) activates protection and discharge. |
| 2 PGOOD1 | VDDQ Power-Good Monitor | Open-drain output asserted low if VDDQ deviates >15% from regulation; used for system power sequencing. |
| 3 PGOOD2 | VTT Power-Good Monitor | Open-drain output asserted low if VTT deviates >10% from regulation; enables safe memory initialization. |
| 4 STDBY | Ultra-Skip Mode Control | When high with SHDN high, enables full VDDQ/VTT operation; low forces ultra-skip and disables VTT output. |
| 5 VTTS | VTT Sense Input | Connects to VTT node for accurate regulation to VREFIN or VCSL/2; critical for termination voltage stability. |
| 6 VTTR | Reference Buffer Output | Sources/sinks ±3mA; tracks VCSL/2 or REFIN to provide precise DDR bus reference voltage. |
| 8 VTT | VTT Power Output | ±2A source/sink output; connects directly to memory termination network; requires PGND2 return path. |
| 10 REFIN | External Reference Input | 0.5V–1.5V input sets VTTR/VTTS; tied to VCC for internal VCSL/2 division (SSTL-18 or SSTL-15). |
| 11 FB | VDDQ Feedback Input | Regulates to 1.0V; connect to AGND for 1.5V, VCC for 1.8V, or resistor divider for adjustable output. |
| 14 TON | Frequency Setting Input | Resistor-to-VIN sets switching frequency (200–600kHz); enables trade-off between efficiency and EMI. |
| 15 DH / 18 DL | Gate Drivers | DH drives high-side MOSFET (BST–LX swing); DL drives synchronous rectifier (VDD–PGND1 swing). |
| 19 VDD | DL Gate Driver Supply | +4.5V to +5.5V supply for low-side driver; bypassed with ≥1μF ceramic capacitor to PGND1. |
| 23 VCC | Main Controller Supply | +4.5V to +5.5V analog supply; bypassed to AGND; UVLO triggers at 4.0V–4.4V. |
| 24 SHDN | Global Shutdown Control | Pulled high for normal operation; falling edge initiates soft-stop ramp and enters <1μA shutdown state. |

FAQ
What is the maximum input voltage rating for the MAX17000ETG+TG05?
The MAX17000ETG+TG05 supports an absolute maximum input voltage of 26V on the VIN pin, with recommended operating range of 3V to 26V. This allows direct connection to common notebook adapter rails (7V–20V) while providing margin for transients. The VCC and VDD supplies are limited to 4.5V–5.5V and must be independently regulated.
How does the MAX17000ETG+TG05 achieve 100ns load-step response on VDDQ?
The MAX17000ETG+TG05 achieves 100ns VDDQ load-step response through its proprietary Quick-PWM™ constant-on-time architecture, which eliminates loop compensation delays inherent in voltage-mode or current-mode PWMs. The controller senses inductor current directly and adjusts duty cycle within one switching cycle, enabling rapid correction without sacrificing frequency stability.
Can the MAX17000ETG+TG05 support both DDR2 and DDR3 memory simultaneously?
No - the MAX17000ETG+TG05 is configured per application: VDDQ output is set to either 1.5V (DDR2/SSTL-15) or 1.8V (DDR2/SSTL-18) via FB pin connection, and VTTR/VTTS track accordingly. A single MAX17000ETG+TG05 cannot dynamically switch between DDR2 and DDR3 standards; design selection is fixed at layout.
What is the purpose of the VTTS pin on the MAX17000ETG+TG05?
The VTTS pin on the MAX17000ETG+TG05 is the VTT output sense terminal. It must be connected directly to the VTT net near the memory DIMM to close the feedback loop for accurate regulation. This Kelvin sensing eliminates IR drop errors from PCB traces, ensuring ±5mV deadband operation and stable termination under dynamic load conditions.
Does the MAX17000ETG+TG05 include thermal protection?
Yes, the MAX17000ETG+TG05 includes thermal shutdown protection with a trip threshold of 160°C and 15°C hysteresis. When junction temperature exceeds 160°C, the device disables all outputs and enters a latched fault state until SHDN is cycled. This protects against sustained overload or inadequate heatsinking in compact notebook layouts.
