Product details
Overview
MAX17290ETCF+T 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, integrated 5V PVL regulator, and supports external synchronization via FSET/SYNC pin. It is used in telecom power supplies requiring robust transient protection and precise output regulation.
For engineers reviewing the MAX17290ETCF+T datasheet, MAX17290ETCF+T pinout, MAX17290ETCF+T application, or MAX17290ETCF+T equivalent, key selection criteria include its 2.5V–36V input range, 2.5MHz max switching frequency, 42V input transient tolerance, programmable slope compensation, and 180° SYNCO output for multiphase operation.
Technical Context
The MAX17290ETCF+T implements constant-frequency peak current-mode control with internal transconductance error amplifier (700µS gm), 1V FB reference accuracy (±1%), and adjustable soft-start (9ms fixed). Its oscillator supports resistor-programmed frequencies from 100kHz to 1MHz (MAX17290 variant) and includes spread-spectrum modulation (±6%) to reduce EMI peaks.
It integrates a 5V/100mA LDO (PVL) for gate drive and bias, supports external nMOSFET driving with 750mA source / 1000mA sink capability, and provides comprehensive protection including hiccup-mode overcurrent, thermal shutdown (165°C), and OVP via dedicated pin - though OVP functionality is absent in TCF/TCE variants per pinout documentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 36V continuous; extends to 2.5V when bootstrapped - enables direct operation from low-voltage battery sources or post-regulated rails. |
| Switching Frequency | 100kHz to 1MHz (resistor-programmable); supports external sync up to 1MHz - allows EMI optimization and multi-converter phase alignment. |
| Shutdown Current | 4µA typical - minimizes system standby power in always-on or battery-backed applications. |
| PVL Regulator Output | 4.7V to 5.45V at 10mA - powers external MOSFET gate and internal circuitry; eliminates need for auxiliary bias supply. |
| Current-Sense Threshold | 212mV to 288mV - sets precise overcurrent limit; combined with ISNS blanking (60ns) ensures reliable detection under fast transients. |
| Thermal Shutdown | 165°C with 10°C hysteresis - protects IC and external FETs during overload or poor heatsinking conditions. |
| PGOOD Accuracy | ±5% window (85–95% rising, 80–90% falling) - provides reliable power-rail monitoring for downstream sequencing and fault reporting. |
Pinout & Package
MAX17290ETCF+T is housed in a 12-pin 3mm × 3mm TQFN-EP package with exposed pad connected to GND for thermal management. Pin assignments are validated per Maxim's official pinout diagrams for ETCE/F variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| EN | Active-high enable | Logic- or high-voltage compatible (–0.3V to +42V); enables ultra-low 4µA shutdown state. |
| GND | Ground reference | Common return for analog, power, and exposed pad; requires low-impedance PCB plane connection. |
| DRV | nMOS gate driver output | Swings between PVL (~5V) and GND; drives external FET with 750mA source / 1000mA sink capability. |
| PVL | Internal 5V regulator output | Supplies DRV and external circuitry; requires ≥2.2µF ceramic capacitor placed adjacent to pin. |
| ISNS | Current-sense input | Monitors voltage across external sense resistor; includes 60ns leading-edge blanking to reject switching noise. |
| REFIN | Reference input | Accepts 0.5V–2V external voltage to set output regulation point; tied to PVL for default 1V FB reference. |
| PGOOD | Open-drain power-good flag | Asserts after soft-start when VOUT reaches ≥90% of target; sinks current during fault or EN=low. |
| FSET/SYNC | Frequency set / sync input | Resistor-programmed oscillator or external clock input (220kHz–1MHz); triggers DRV on falling edge with 60ns delay. |
| COMP | Error amplifier output | Connects to RC compensation network between COMP and GND for loop stability. |
| FB | Feedback input | Regulated to 1V (or REFIN) during operation; connects to resistor divider from VOUT to set output voltage. |
| EP | Exposed thermal pad | Internally connected to GND; must be soldered to large copper area for thermal performance (θJA = 68°C/W on 4-layer board). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX17292ETCF+T | Higher switching frequency range (1MHz–2.5MHz); same pinout and feature set except no OVP pin - TCF variant lacks OVP functionality. | Better suited for ultra-compact designs requiring smallest possible inductors/capacitors; not appropriate where overvoltage protection is mandatory. | Select MAX17292ETCF+T when board space is constrained and OVP is handled externally or not required. |
| LM5122MMX/NOPB | Wider input range (3V–65V); integrated high-side gate driver; no internal PVL regulator; requires external bias supply. | Preferred for ultra-high-VIN applications like solar MPPT or industrial 48V systems; lacks integrated 5V LDO, increasing BOM count. | Choose LM5122MMX/NOPB when input exceeds 36V or when higher integration of gate drive is needed without PVL dependency. |
Compared with MAX17290ETCF+T, MAX17292ETCF+T offers higher-frequency operation for smaller passives but omits OVP, while LM5122MMX/NOPB supports wider VIN and higher voltage transients but requires external bias and adds complexity in gate-drive design.

FAQ
What is the maximum input voltage transient rating for MAX17290ETCF+T?
The MAX17290ETCF+T is rated for 42V input voltage transients, protecting against surge events such as load dump in automotive systems or lightning-induced spikes in telecom infrastructure. This rating applies regardless of steady-state input voltage and is validated per Absolute Maximum Ratings - operation beyond 42V may cause permanent damage.
Does MAX17290ETCF+T include overvoltage protection (OVP) functionality?
No, the MAX17290ETCF+T does not include OVP functionality. Per Maxim's official pinout documentation, the TCF and TCE variants omit the OVP pin - only TCC/D versions provide this feature. Designers requiring OVP must use MAX17290ETCC+T or implement external protection circuitry.
What is the purpose of the REFIN pin on MAX17290ETCF+T?
The REFIN pin on MAX17290ETCF+T accepts an external reference voltage between 0.5V and 2V to dynamically adjust the feedback regulation point - enabling on-the-fly output voltage tuning or precise tracking of variable references. When tied to PVL, it defaults to 1V FB regulation for standard boost configurations.
Can MAX17290ETCF+T operate with input voltage below 4.5V?
Yes, MAX17290ETCF+T can operate with input as low as 2.5V in bootstrapped mode, where the converter's output supplies the SUP pin. This mode bypasses the internal UVLO threshold and relies on PVL regulation stability - confirmed in the General Description and Detailed Description sections of the datasheet.
What package type and thermal characteristics apply to MAX17290ETCF+T?
MAX17290ETCF+T uses a 12-pin 3mm × 3mm TQFN-EP package with exposed pad connected to GND. On a four-layer PCB, its junction-to-ambient thermal resistance is 68°C/W and junction-to-case is 11°C/W - requiring adequate copper pour under the EP for reliable operation at full load.
