Product details
Overview
MAX17291BANT+ from Analog Devices is a high-voltage micropower boost converter IC designed for ultra-low-power, space-constrained systems. It delivers 5.5V–20V output from a 1.8V–4.5V input, features 28µA quiescent current, 100mA peak inductor current limit, and true shutdown with 13nA supply current-enabling multi-year battery life in primary-cell IoT sensor nodes.
For engineers reviewing the MAX17291BANT+ datasheet, MAX17291BANT+ pinout, MAX17291BANT+ application, or MAX17291BANT+ equivalent, key selection criteria include its 1.27mm × 0.87mm WLP package, discontinuous conduction mode (DCM) operation, integrated power switch/diode/load switch, and guaranteed -40°C to +125°C operation without derating.
Technical Context
The MAX17291BANT+ employs current-mode control in discontinuous conduction mode (DCM), using a fixed peak inductor current limit of 100mA to regulate output voltage via external resistor divider on FB. Its PFM-based power-save mode maintains high efficiency across light-to-moderate loads.
It integrates an N-channel and P-channel MOSFET pair, a Schottky diode, and an output load switch-enabling true shutdown isolation with no reverse current from OUT to IN. Protection includes output short-circuit response with enforced 1.5µs off-time and thermal lockout at 165°C with 15°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8V to 4.5V - supports single alkaline, Li-SOCl₂, or low-voltage lithium primary cells without pre-regulation |
| Output Voltage Range | 5.5V to 20V - programmable via external resistor divider; enables direct powering of op-amps, RF transceivers, or sensors requiring >5V rails |
| Quiescent Current (IN) | 28µA - sustains >10-year battery life in always-on wake-up sensor applications with 250mAh coin cell |
| Shutdown Current | 13nA - ensures negligible drain during deep sleep, critical for energy-harvesting and long-life deployments |
| Peak Inductor Current Limit | 100mA - sets maximum energy per switching cycle; determines inductor sizing and transient capability |
| Operating Temperature | -40°C to +125°C - qualified for industrial and automotive under-hood environments without thermal derating |
| Package Dimensions | 1.27mm × 0.87mm WLP - smallest available boost converter footprint; reduces PCB area by >60% vs. comparable SOT-23 solutions |
Pinout & Package
MAX17291BANT+ uses a 6-bump wafer-level package (WLP), 3×2 array, 0.4mm pitch, 1.27mm × 0.87mm body size, compatible with standard reflow processes and suitable for automated assembly on high-density PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX | Switching Node | Connects inductor between IN and LX; carries high di/dt pulses; requires minimal trace length and ground plane clearance to reduce EMI |
| IN | Input Supply | Accepts 1.8V–4.5V input; must be bypassed with ≥22µF ceramic capacitor directly to GND for stable startup and ripple suppression |
| EN | Enable Input | Active-high logic control; VIH = 0.82V–1.4V (at VIN); connects to IN if unused to ensure always-on operation |
| FB | Feedback Input | Senses output voltage via resistor divider; internal 1.25V reference enables precise VOUT programming with ±1.25% accuracy |
| OUT | Regulated Output | Delivers regulated 5.5V–20V; connects to ≥4.7µF ceramic capacitor near OUT/GND pins to minimize ripple and stabilize loop |
| GND | Power Ground | Primary return path for input/output currents and feedback network; requires low-impedance Kelvin connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| True Shutdown Mode | Completely isolates OUT from IN with no forward or reverse current path, enabling zero-load leakage during system sleep |
| No Reverse Current from OUT | Prevents backfeed into input source when output voltage exceeds input-critical for multi-rail systems and battery backup configurations |
| Output Short-Circuit Protection | Enforces 100mA peak current limit and 1.5µs minimum off-time during fault, preventing thermal runaway without external circuitry |
| Overtemperature Protection | Locks out operation above 165°C junction temperature with 15°C hysteresis, ensuring safe recovery after thermal stress events |
| 90% Peak Efficiency | Achieved at moderate loads (e.g., 10–30mA), minimizing heat generation and extending battery runtime in compact enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS610995YFFR | Higher IQ (300nA shutdown, 400nA operating), but narrower output range (up to 5.5V only) and no integrated load switch | Best suited for sub-5V output needs where ultra-low IQ dominates over voltage flexibility | Select TPS610995YFFR only when output ≤5.5V and shutdown current <100nA is mandatory |
| LT3467EDD#TRPBF | Higher peak current (600mA), wider input (2.7V–16V), but larger 3mm × 3mm DFN package and 100µA IQ | Appropriate for higher-power, less space-constrained designs needing robust transient response | Choose LT3467EDD#TRPBF when >100mA output current or >4.5V input is required, accepting larger footprint |
Compared with TPS610995YFFR and LT3467EDD#TRPBF, the MAX17291BANT+ uniquely balances ultra-low IQ, high output voltage (up to 20V), true shutdown isolation, and sub-1mm² footprint-making it the only option for miniature, long-life, high-voltage boost applications.

FAQ
What is the absolute maximum output voltage rating for the MAX17291BANT+?
The MAX17291BANT+ has an absolute maximum output voltage rating of +22V referenced to GND, as specified in the Absolute Maximum Ratings table. This allows safe operation up to 20V output while maintaining 2V margin against overvoltage stress. Exceeding 22V may cause permanent damage, even momentarily.
Does the MAX17291BANT+ support adjustable output voltage, and how is it configured?
Yes, the MAX17291BANT+ supports fully adjustable output voltage from 5.5V to 20V using an external resistor divider connected to the FB pin. The internal 1.25V reference sets VOUT = 1.25V × (1 + R1/R2); recommended R1 values are below 475kΩ to minimize FB bias current error and noise susceptibility.
Can the MAX17291BANT+ operate with a 1.5V alkaline battery as input?
No-the MAX17291BANT+ requires a minimum input voltage of 1.8V to enable operation, per its undervoltage lockout (UVLO) threshold of 1.7V (rising) with 100mV hysteresis. A fresh 1.5V alkaline cell falls below this threshold; use only when boosted to ≥1.8V or select a cell type with higher nominal voltage (e.g., lithium iron disulfide).
What protection features are integrated into the MAX17291BANT+?
The MAX17291BANT+ integrates output short-circuit protection (100mA current limit + 1.5µs enforced off-time), overtemperature lockout (165°C trip with 15°C hysteresis), input UVLO (1.7V rising), and true shutdown with no reverse current. These eliminate need for external protection components in most battery-powered designs.
Is the MAX17291BANT+ pin-compatible with other members of the MAX1729x family?
Yes-the MAX17291BANT+ shares identical pinout, package, and footprint with MAX17291AANT+ and MAX17292BANT+, differing only in UVLO threshold and FB accuracy. This allows drop-in replacement within the same family for design optimization without PCB revision.
