Product details
Overview
MAX17291BANT+T from Analog Devices is a high-voltage micropower boost DC-DC converter with True Shutdown, 1.8V–4.5V input range, 5.5V–20V output range, 100mA peak inductor current limit, and 28µA quiescent supply current. It integrates power switch, power diode, and output load switch for ultra-low-power sensor modules requiring regulated high-voltage rails from single primary cells.
For engineers reviewing the MAX17291BANT+T datasheet, MAX17291BANT+T pinout, MAX17291BANT+T application, or MAX17291BANT+T equivalent, key selection criteria include shutdown current (13nA), output short-circuit protection, discontinuous conduction mode operation, and 1.27mm × 0.87mm 6-bump WLP package compatibility with space-constrained IoT sensor designs.
Technical Context
The MAX17291BANT+T employs current-mode control in discontinuous conduction mode (DCM) with pulse frequency modulation (PFM) for light-load efficiency. Its on-time is determined by a fixed 100mA peak inductor current limit, and off-time ends when inductor current reaches zero.
It features undervoltage lockout (1.7V rising threshold, 100mV hysteresis), thermal shutdown at 165°C (15°C hysteresis), and true shutdown that disconnects OUT from IN with no reverse current-enabled via active-high EN pin and enforced by integrated load switch.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8V to 4.5V - supports single alkaline, lithium primary, or low-voltage secondary cells without external LDO pre-regulation. |
| Output Voltage Range | 5.5V to 20V - programmable via external resistor divider (FB = 1.25V reference), enabling direct biasing of op-amps, sensors, or RF front-ends. |
| Quiescent Supply Current | 28µA at VIN - enables multi-year battery life in always-on sub-100µA IoT endpoints. |
| Shutdown Current | 13nA into IN - ensures negligible battery drain during deep sleep, critical for energy-harvesting and coin-cell applications. |
| Peak Inductor Current Limit | 100mA - sets maximum energy transfer per cycle and defines startup inrush and short-circuit current limiting behavior. |
| Efficiency | 90% peak - achieved across wide load range due to PFM operation and low RDS(ON) (450mΩ N-FET, 320mΩ P-FET). |
| Operating Temperature | −40°C to +125°C - qualified for industrial and automotive under-hood sensor environments. |
| Package | 1.27mm × 0.87mm 6-bump WLP (0.4mm pitch) - smallest footprint boost converter in its voltage class, compatible with 0201-level layout density. |
Pinout & Package
MAX17291BANT+T is housed in a 1.27mm × 0.87mm, 6-bump wafer-level package (WLP) with 0.4mm pitch and bottom-side solder bumps. The package supports reflow assembly and provides minimal thermal resistance (θJA = 95.15°C/W on four-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX | Switching node | Connects inductor between IN and LX; carries high di/dt switching current; requires shortest possible trace to minimize EMI and voltage overshoot. |
| IN | Input supply | Accepts 1.8V–4.5V source; must be bypassed with ≥22µF ceramic capacitor directly to GND to suppress input ripple and support peak current delivery. |
| EN | Enable control | Active-high logic input (VIH = 0.82V–1.4V); tie to IN if enable unused; controls True Shutdown state and isolates OUT from IN with <13nA leakage. |
| FB | Feedback sense | Monitors voltage divider from OUT to GND; internal 1.25V reference enables precise output programming; sensitive to noise-requires Kelvin ground routing. |
| OUT | Regulated output | Delivers 5.5V–20V; connects to ≥4.7µF ceramic capacitor directly to GND; output load switch disconnects this node during shutdown. |
| GND | Power ground | Primary return path for IN, OUT, and LX currents; must connect to solid ground plane with multiple vias to minimize impedance and thermal rise. |
Key Features
| Feature | Design Value |
|---|---|
| True Shutdown Mode | Physically disconnects OUT from IN using integrated load switch-eliminates reverse current and reduces shutdown current to 13nA. |
| Output Short-Circuit Protection | Clamps peak inductor current to 100mA and enforces 1.5µs minimum off-time during VOUT ≈ 0V, preventing thermal runaway during fault conditions. |
| Discontinuous Conduction Mode (DCM) | Ensures stable regulation at ultra-light loads (<10µA) without burst-mode noise; simplifies loop compensation and improves transient response predictability. |
| Integrated Power Diode | Eliminates need for external Schottky diode-reducing BOM count, PCB area, and forward voltage drop losses in compact sensor modules. |
| Overtemperature Lockout | Shuts down at 165°C junction temperature with 15°C hysteresis; resumes operation only after cooling to ~150°C-prevents permanent damage in sealed enclosures. |
| UVLO with Hysteresis | Enables at VIN ≥ 1.7V (typ), disables at VIN ≤ 1.6V (typ); 100mV hysteresis prevents oscillation during battery voltage sag or cold-start conditions. |

FAQ
What is the absolute maximum input voltage rating for the MAX17291BANT+T?
The MAX17291BANT+T has an absolute maximum input voltage (IN to GND) of +6V. Exceeding this rating-even momentarily-may cause permanent damage. The device operates only within its specified 1.8V–4.5V input range; the 6V limit applies solely to survival under fault or transient conditions, not functional operation.
Does the MAX17291BANT+T support adjustable output voltage, and how is it configured?
Yes, the MAX17291BANT+T supports fully adjustable output voltage from 5.5V to 20V using an external resistor divider connected to the FB pin. With a precise 1.25V internal reference, output voltage is set by R1 and R2 per the formula: R2 = ((VOUT / 1.25V) – 1) × R1. MAX17291BANT+T requires R1 ≤ 475kΩ for optimal accuracy and noise immunity.
How does the True Shutdown feature of the MAX17291BANT+T differ from standard shutdown modes?
True Shutdown in the MAX17291BANT+T physically disconnects the output (OUT) from the input (IN) using an integrated load switch-eliminating both forward and reverse current paths. This achieves 13nA shutdown current and prevents backfeeding, unlike conventional boost converters that retain parasitic diode conduction paths. MAX17291BANT+T ensures zero load current draw during sleep states.
Can the MAX17291BANT+T drive a 100mA continuous load?
No-the MAX17291BANT+T has a 100mA peak inductor current limit, not a continuous output current rating. Continuous output current depends on input/output voltage ratio, inductor value, and duty cycle. At 12V out from 3.6V in, typical continuous output is ~25mA. MAX17291BANT+T is optimized for ultra-low average current (µA–mA) sensor bias, not high-current loads.
What thermal protection mechanisms are built into the MAX17291BANT+T?
The MAX17291BANT+T incorporates overtemperature lockout that disables switching when junction temperature exceeds +165°C. After shutdown, operation resumes only when temperature falls below +150°C (15°C hysteresis). This protects against sustained overload or poor PCB thermal design. Thermal shutdown is independent of input voltage and load conditions.
