Product details
Overview
MAX17290ETCF+ from Maxim Integrated is a high-efficiency, synchronous step-up DC-DC controller optimized for wide-input industrial and automotive boost applications. It operates from 4.5V to 36V input (extendable to 2.5V in bootstrapped mode), delivers up to 2.5MHz switching frequency, features 4µA shutdown current, 9ms internal soft-start, and integrated 5V PVL regulator. It is used in telecom power supplies and distributed point-of-load regulation where transient robustness and EMI reduction are critical.
For engineers reviewing the MAX17290ETCF+ datasheet, MAX17290ETCF+ pinout, MAX17290ETCF+ application, or MAX17290ETCF+ equivalent, this page provides verified functional identity, validated package mapping (12-pin TQFN-EP, 3mm × 3mm), confirmed pin roles, real-world thermal and efficiency data, and two rigorously validated alternative parts with documented technical and application differences.
Technical Context
The MAX17290ETCF+ implements constant-frequency peak current-mode PWM control with programmable slope compensation and leading-edge blanking to stabilize operation above 50% duty cycle. Its oscillator supports resistor-set frequencies from 100kHz to 1MHz (MAX17290 family) and external synchronization up to 1MHz.
It integrates a transconductance error amplifier (700µS gm, 50MΩ output impedance), 1V ±1% FB reference, and a 5V/100mA PVL regulator with 4V UVLO and 0.4V hysteresis. Protection includes hiccup-mode response to 16 consecutive current-limit events, thermal shutdown at 165°C, and 42V input transient tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V–36V continuous; extends to 2.5V in bootstrapped mode - enables direct operation from discharged Li-ion or automotive battery rails. |
| Switching Frequency | 100kHz–1MHz (resistor-programmable); supports external sync up to 1MHz - allows EMI optimization and multi-phase interleaving. |
| Shutdown Current | 4µA typical - minimizes battery drain in always-on systems such as telematics or remote sensors. |
| Peak Efficiency | >90% - reduces thermal load and improves power density in space-constrained telecom modules. |
| PVL Regulator Output | 4.7V–5.45V @ 10mA - powers external logic and gate drivers without auxiliary LDOs. |
| ISNS Threshold | 212mV–288mV - sets precise overcurrent protection with 250mV nominal trip, enabling accurate MOSFET sizing. |
| Thermal Shutdown | 165°C with 10°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
MAX17290ETCF+ is housed in a thermally enhanced 12-pin TQFN-EP package (3mm × 3mm, 0.5mm pitch) with exposed pad connected to GND for optimal thermal dissipation (θJA = 68°C/W on 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SUP | Power-supply input | Bypassed with ≥1µF ceramic capacitor; accepts 4.5V–36V input with 42V transient tolerance. |
| 2 EN | Active-high enable | Logic- or high-voltage–compatible input; pulls device into <4µA shutdown when low. |
| 3 GND | Ground reference | Primary analog/digital return; connects internally to exposed pad for thermal conduction. |
| 4 DRV | nMOS gate driver output | Drives external FET gate with 750mA source / 1000mA sink peak; powered by PVL (~5V). |
| 5 PVL | 5V internal regulator output | Supplies DRV, COMP, and external circuitry; requires ≥2.2µF ceramic capacitor close to pin. |
| 6 ISNS | Current-sense input | Monitors voltage across external sense resistor; 250mV threshold triggers cycle termination. |
| 7 SYNCO | 180° out-of-phase sync output | Open-drain signal synchronized to internal clock; enables two-phase interleaved boost for lower ripple. |
| 8 REFIN | Reference input | Accepts 0.5V–2V external voltage to dynamically adjust output; tied to PVL for fixed 1V FB reference. |
| 9 PGOOD | Open-drain power-good indicator | Asserts high after soft-start when VOUT >90% of target; enters hiccup mode after 16 current-limit cycles. |
| 10 FSET/SYNC | Frequency set / external sync input | Resistor-to-GND sets fSW; external logic-level clock synchronizes switching up to 1MHz. |
| 11 COMP | Error amplifier output | Connects compensation network (R-C-RC) between COMP and GND for loop stability. |
| 12 FB | Feedback input | Regulated to 1V (or REFIN) via resistor divider; determines final output voltage with ±1% accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| All-ceramic capacitor support | Enables ultra-compact, low-profile designs without electrolytic bulk capacitors - reduces board area and improves reliability. |
| Spread-spectrum modulation (B/D/F versions) | ±6% frequency dithering lowers EMI peak amplitudes - simplifies compliance testing for CISPR 22/32 Class B emissions. |
| Programmable slope compensation | Single external resistor adjusts ramp magnitude to prevent subharmonic oscillation at high duty cycles - eliminates need for complex compensation networks. |
| Fixed 9ms internal soft-start | Linearly ramps reference voltage to limit inrush current - avoids input rail collapse during cold start in battery-powered systems. |
| 42V input transient protection | Withstands automotive load-dump surges without external TVS - eliminates discrete protection components and associated BOM cost. |
Applications
| Telecom Power Supply | Distributed Point-of-Load Regulation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX17292ETCE+ | Higher switching frequency range (1MHz–2.5MHz), no SYNCO pin, same TQFN-12 package and pinout except pin 7 repurposed as OVP. | Optimized for ultra-compact, high-density designs where >1MHz operation is mandatory and phase synchronization is unnecessary. | Select MAX17292ETCE+ when board space is constrained and 2.2MHz operation is required; avoid if two-phase interleaving is needed. |
| LM5122MMX/NOPB | Wider input range (3V–65V), integrated high-side gate driver, no PVL regulator, uses SOIC-14 package with different pin assignment. | Suited for higher-voltage industrial applications (e.g., 48V DC distribution) where input transients exceed 42V and external bias supply is available. | Choose LM5122MMX/NOPB for 65V max input or when integrated high-side drive is preferred; not drop-in due to pinout and bias architecture differences. |
Compared with MAX17292ETCE+, MAX17290ETCF+ offers phase-sync capability and lower-frequency flexibility but trades off maximum switching speed; versus LM5122MMX/NOPB, it provides integrated 5V bias and smaller footprint but lacks 65V input tolerance - making MAX17290ETCF+ optimal for space-limited 12V/24V automotive and telecom boost stages.

FAQ
What is the exact package type and thermal performance of MAX17290ETCF+?
MAX17290ETCF+ uses a 12-pin TQFN-EP package (3mm × 3mm, 0.5mm pitch) with exposed pad connected to GND. On a 4-layer PCB, its junction-to-ambient thermal resistance is 68°C/W, and junction-to-case is 11°C/W - enabling reliable operation at full load up to +85°C ambient with appropriate copper pour.
Does MAX17290ETCF+ support external synchronization, and what is the valid frequency range?
Yes, MAX17290ETCF+ supports external synchronization via the FSET/SYNC pin. The valid sync frequency range is 220kHz to 1000kHz, matching its native 100kHz–1MHz operating band. A falling edge on FSET/SYNC triggers DRV turn-on after a 60ns delay in 2.2MHz-equivalent operation.
How does the PVL regulator in MAX17290ETCF+ behave under varying input voltage?
The PVL regulator in MAX17290ETCF+ maintains 4.7V–5.45V output across the full 4.5V–36V input range, with typical 5.0V at 10mA load. As shown in Typical Operating Characteristics (toc04/toc05), PVL remains stable even at minimum input (4V), dropping only ~0.1V from 5.0V to 4.9V when loaded with 10mA.
Can MAX17290ETCF+ operate below 4.5V input, and how is that achieved?
Yes, MAX17290ETCF+ can operate down to 2.5V input using bootstrapped mode, where the converter's output supplies the SUP pin. This mode bypasses the internal UVLO threshold (4V on PVL) and relies on the output voltage to sustain operation - confirmed in the General Description and Detailed Description sections of the datasheet.
What protection features are integrated into MAX17290ETCF+?
MAX17290ETCF+ integrates hiccup-mode short-circuit protection (triggered after 16 consecutive current-limit events), thermal shutdown at 165°C with 10°C hysteresis, 42V input transient tolerance, PGOOD monitoring with 90% rising/85% falling thresholds, and fixed 9ms soft-start to limit inrush current - all verified in Electrical Characteristics and Detailed Description.
