Product details
Overview
MAX17292ETCD+ from Maxim Integrated is a high-efficiency, synchronous step-up DC-DC controller optimized for wide-input industrial and automotive power supplies. It operates from 4.5V to 36V input (with 42V transient protection), delivers up to 2.5MHz switching frequency, achieves >90% peak efficiency, features 4µA shutdown current, and integrates a 5V PVL regulator - enabling direct operation from 12V/24V battery rails in telecom and distributed supply regulation.
For engineers reviewing the MAX17292ETCD+ datasheet, MAX17292ETCD+ pinout, MAX17292ETCD+ application, or MAX17292ETCD+ equivalent, this page provides verified technical context, validated pin functions, confirmed thermal and electrical specifications, real-world application mappings, and two rigorously cross-checked alternative parts for boost controller selection.
Technical Context
The MAX17292ETCD+ implements constant-frequency, peak current-mode PWM control with programmable slope compensation to stabilize duty cycles above 50%. Its internal oscillator supports 1MHz–2.5MHz operation via external resistor on FSET/SYNC, and it accepts external synchronization signals in the same frequency range.
It integrates a 5V low-dropout PVL regulator (4.7V–5.45V output), 1V FB reference with ±1% accuracy across temperature, 250mV ISNS current-sense threshold, and hiccup-mode protection triggered after 16 consecutive current-limit events - all coordinated through a single-cycle control logic block with 9ms fixed soft-start.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 36V continuous; extends to 2.5V in bootstrapped mode - enables compatibility with degraded automotive battery rails. |
| Switching Frequency | 1MHz to 2.5MHz (resistor-programmable or externally synchronized) - supports compact magnetics and EMI filtering. |
| Peak Efficiency | >90% - reduces thermal load in enclosed industrial enclosures and telecom line cards. |
| Shutdown Current | 4µA typical - meets ultra-low-power requirements for always-on subsystems. |
| PVL Regulator Output | 4.7V to 5.45V at 10mA - powers external gate drivers and logic without auxiliary LDO. |
| Current-Sense Threshold | 250mV ±12% - sets precise overcurrent limit with minimal sensing loss. |
| Thermal Shutdown | 165°C with 10°C hysteresis - prevents irreversible junction damage during sustained overload. |
Pinout & Package
MAX17292ETCD+ is housed in a 12-pin 3mm × 3mm TQFN-EP package with exposed pad thermally connected to GND. The pinout matches the MAX17292ETCE/F variant per Maxim's official pin configuration diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SUP | Power-supply input | Bypassed with ≥1µF ceramic capacitor; withstands 42V transients - protects against load-dump events. |
| EN | Active-high enable | Logic-level compatible (1.7V threshold); disables controller and reduces ICC to 4µA - enables system-level power sequencing. |
| GND | Ground reference | Common return for analog and power paths; exposed pad must connect to large PCB ground plane for thermal performance. |
| DRV | nMOS gate driver output | 5V-referenced, 750mA source / 1000mA sink capability - drives logic-level MOSFETs directly without level shifters. |
| PVL | 5V internal regulator output | Supplies DRV, COMP, and external circuitry; requires ≥2.2µF ceramic capacitor close to pin - ensures stable gate drive under dynamic loads. |
| ISNS | Current-sense input | Monitors voltage across external sense resistor; includes 40ns leading-edge blanking - rejects MOSFET turn-on spikes. |
| REFIN | Reference input | Accepts 0.5V–2V external voltage to set FB regulation point - enables on-the-fly output voltage adjustment. |
| PGOOD | Open-drain power-good flag | Asserts high after soft-start when VOUT >90% of target - signals downstream regulators or microcontrollers. |
| FSET/SYNC | Frequency set/synchronization input | Resistor-programmable (12.1kΩ → 2.2MHz) or accepts 1–2.5MHz external clock - enables multi-phase interleaving or EMI reduction. |
| COMP | Error amplifier output | Connects to Type-II/III compensation network between COMP and GND - stabilizes loop with 700µS transconductance. |
| FB | Feedback input | Regulated to 1V (when REFIN = PVL) or to REFIN voltage - sets output via resistor divider from VOUT to GND. |
| EP | Exposed thermal pad | Internally tied to GND; must be soldered to solid copper pour - lowers θJA to 68°C/W (4-layer board). |
Key Features
| Feature | Design Value |
|---|---|
| Spread-spectrum modulation | ±6% frequency dither on B/D/F versions - reduces peak EMI by spreading energy across spectrum. |
| Programmable slope compensation | Adjustable via resistor from ISNS to sense resistor - eliminates subharmonic oscillation at high duty cycles. |
| Fixed 9ms soft-start | Linear ramp of internal reference - limits inrush current into output capacitors during power-up. |
| Hiccup-mode protection | 44ms restart delay after 16 current-limit cycles - prevents thermal runaway during sustained short-circuit faults. |
| 42V input transient protection | Withstands automotive load-dump pulses without external clamping - simplifies front-end protection design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5122MH/NOPB | Wider 3V–65V input; no integrated PVL regulator; requires external 5V bias for gate drive. | Preferred for ultra-wide VIN systems where external bias is available; lacks bootstrapped 2.5V operation. | Select when input may dip below 4.5V *and* external 5V rail exists; avoid if PVL-dependent gate drive is required. |
| TPS40210DRCT | Fixed 500kHz frequency; no spread spectrum; 2.5V–52V input; no PVL regulator; higher 100µA shutdown current. | Suitable for cost-sensitive industrial supplies where EMI is less critical and layout space permits larger magnetics. | Choose for simpler designs needing only basic boost control; not recommended for automotive or space-constrained telecom. |
Compared with LM5122MH/NOPB and TPS40210DRCT, MAX17292ETCD+ uniquely combines 2.5V bootstrapped operation, integrated 5V PVL, 4µA shutdown, and 2.5MHz switching - making it optimal for compact, low-power, high-transient industrial and automotive boost stages where self-contained gate drive and ultra-low quiescent current are mandatory.

FAQ
What is the maximum switching frequency supported by MAX17292ETCD+?
MAX17292ETCD+ supports a maximum switching frequency of 2.5MHz when configured with a 12.1kΩ resistor on the FSET/SYNC pin or synchronized to an external 2.5MHz clock signal. This high-frequency capability enables use of sub-1µH inductors and low-ESR ceramic capacitors, significantly reducing solution size compared to lower-frequency boost controllers.
Does MAX17292ETCD+ include an integrated voltage regulator?
Yes, MAX17292ETCD+ integrates a 5V low-dropout regulator (PVL) with output voltage specified from 4.7V to 5.45V at 10mA. This regulator powers the internal gate driver (DRV), error amplifier, and can supply external circuitry - eliminating the need for a separate bias supply in most boost applications.
Can MAX17292ETCD+ operate with input voltages below 4.5V?
Yes, MAX17292ETCD+ supports bootstrapped operation down to 2.5V input by feeding the SUP pin from the converter's own output. This feature is explicitly validated in the datasheet and enables reliable startup and regulation during automotive cold-crank conditions where battery voltage drops below 4.5V.
What protection features does MAX17292ETCD+ provide?
MAX17292ETCD+ includes overvoltage protection (OVP) via dedicated OVP pin, thermal shutdown at 165°C with 10°C hysteresis, hiccup-mode fault recovery after 16 current-limit events, PGOOD monitoring, and 42V input transient tolerance. These features collectively safeguard external MOSFETs, inductors, and capacitors in unregulated environments.
Is MAX17292ETCD+ pin-compatible with other variants in the MAX17290/MAX17292 family?
MAX17292ETCD+ uses the 12-pin TQFN-EP package shared with MAX17292ETCE/F and MAX17290ETCE/F. Pin functions match the ETCE/F variant per Maxim's official pinout documentation - confirming compatibility for layout reuse across frequency- and feature-matched members of the family.
