Product details
Overview
MAX17227AANT+T from Maxim Integrated is a nanoPower synchronous boost converter IC designed for ultra-low-power battery-powered systems. It delivers up to 2A peak inductor current, features True Shutdown™ with 1nA input shutdown current, operates from 400mV startup voltage, and achieves 96% peak efficiency - ideal for wearable audio and IoT sensor nodes requiring multi-year battery life.
For engineers reviewing the MAX17227AANT+T datasheet, MAX17227AANT+T pinout, MAX17227AANT+T application, or MAX17227AANT+T equivalent, key selection criteria include its 350nA output-referred quiescent current, single-resistor programmable output (2.3V–5.5V), cycle-by-cycle current limiting, short-circuit protection, and dual-package availability (6-bump WLP / 8-pin TDFN) across –40°C to +125°C.
Technical Context
The MAX17227AANT+T implements an adaptive on-time pulse-frequency-modulation (PFM) control scheme that dynamically transitions between Ultra-Low-Power Mode (ULPM), Low-Power Mode (LPM), and High-Power Mode (HPM) based on load current - enabling 90% efficiency at 500μA and stable regulation down to 10μA. Its internal architecture integrates a high-side switch (95mΩ RDS(ON)) and low-side synchronous rectifier (50mΩ RDS(ON)) with zero-crossing detection (25–75mA threshold) and thermal shutdown at 165°C.
True Shutdown™ disconnects OUT from IN bidirectionally: no forward conduction and no reverse current even when VOUT > VIN, eliminating external load switches. Output voltage is set via a single resistor (RSEL) tied to GND, supporting 32 discrete settings from 2.3V to 5.5V in 100mV steps - with ULPM disabled only for 5.4V/5.5V targets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 400mV to 5.5V - supports direct harvesting from single-cell Li-SOCl₂, NiMH, or energy-harvesting sources. |
| Peak Inductor Current Limit | 2A - enables robust transient response and high output power into 5V/850mA loads at 3V input. |
| Quiescent Current (IQ) | 350nA (output-referred) - extends battery life in always-on sensor nodes with microamp-level average current draw. |
| Shutdown Current | 1nA - preserves battery charge during extended system sleep without external isolation. |
| Output Voltage Range | 2.3V to 5.5V, adjustable via single RSEL resistor - reduces BOM count and PCB area vs. dual-resistor feedback networks. |
| Startup Input Voltage | 880mV - allows cold-start from partially discharged batteries or low-voltage energy harvesters. |
| Efficiency | 96% peak, ≥90% at 500μA - maintains high conversion efficiency across three orders of magnitude load range. |
| Operating Temp | –40°C to +125°C - qualified for industrial and automotive-adjacent edge-node deployments. |
Pinout & Package
The MAX17227AANT+T is supplied in a 6-bump Wafer-Level Package (WLP), 1.58mm × 0.89mm, 0.4mm pitch, 3×2 bump array. This ultra-compact package minimizes board space for wearables and miniaturized IoT modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT | Regulated output node | Connects to 22μF X7R ceramic capacitor; supplies regulated voltage to downstream circuitry. |
| LX | Switching node | Drives external 1.0μH inductor; requires low-inductance layout to minimize switching losses and EMI. |
| GND | Power ground | Main return path for high-current switching loop; must be low-impedance and thermally coupled to PCB copper. |
| RSEL | Voltage select input | Single resistor to GND sets output voltage (2.3V–5.5V); total capacitance must be <2pF for reliable detection. |
| IN | Input supply | Accepts 400mV–5.5V source; connects to 22μF input capacitor to stabilize input during pulsed loading. |
| EN | Enable control | Logic-high (>0.6V) enables operation; logic-low (<0.55V) activates True Shutdown with 1nA leakage. |
Key Features
| Feature | Design Value |
|---|---|
| True Shutdown™ | Bidirectional isolation: zero forward/reverse current between IN and OUT, eliminating need for external load switch in battery-critical designs. |
| Adaptive PFM Control | Three-mode operation (ULPM/LPM/HPM) automatically optimizes switching frequency and on-time to sustain ≥90% efficiency from 10μA to 850mA load. |
| Single-Resistor Output Setting | 32 precise output voltages (2.3V–5.5V) selected with one standard 1% resistor - cuts feedback network size by 50% and eliminates divider current loss. |
| Integrated Protection | Cycle-by-cycle current limit (2A), output short-circuit detection (VOUT < VIN –1V), and thermal shutdown (165°C) prevent damage under fault conditions without external components. |
| Ultra-Low Startup Voltage | 880mV minimum startup into 3kΩ load - enables reliable operation from weak or aging primary cells and ambient energy harvesters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanoPower boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS610995YFFR | 300nA IQ, 1.2A peak current, fixed 3.3V/5.0V options only; no RSEL programmability. | Lacks adjustable output - requires separate SKUs for each voltage; better suited for high-volume fixed-voltage designs. | Select when strict 300nA IQ is mandatory and output voltage is invariant across product variants. |
| LTC3525EDC-3.3#TRMPBF | 600nA IQ, 400mA peak current, fixed 3.3V output; no True Shutdown or short-circuit protection. | Lower peak current limits use cases to sub-100mA loads; requires external reverse-blocking diode for shutdown isolation. | Select for cost-sensitive, low-power applications where 400mA output suffices and external protection is acceptable. |
Compared with TPS610995YFFR and LTC3525EDC-3.3#TRMPBF, the MAX17227AANT+T uniquely combines 2A peak current, single-resistor programmability, True Shutdown, and integrated short-circuit protection - making it optimal for flexible, high-reliability, battery-constrained edge devices.

FAQ
What is the minimum input voltage required for the MAX17227AANT+T to start up?
The MAX17227AANT+T starts up with a minimum input voltage of 880mV into a 3kΩ load. Below this threshold, the device cannot initiate switching. At input voltages between 880mV and 2.0V, operation is load-current limited - meaning heavy loads may prevent the output from reaching its target voltage until VIN increases or load decreases. This capability enables reliable cold-start from nearly depleted primary cells.
How does True Shutdown™ work in the MAX17227AANT+T, and what is its benefit?
True Shutdown™ in the MAX17227AANT+T completely isolates the output from the input in both directions: no forward current flows from IN to OUT, and no reverse current flows from OUT to IN - even if VOUT is biased above VIN. This is achieved through proprietary synchronous rectifier control, eliminating body-diode leakage. The result is 1nA shutdown current, preserving battery energy without requiring external load switches or blocking diodes.
Can the MAX17227AANT+T be used with a 5.5V output setting, and are there any trade-offs?
Yes, the MAX17227AANT+T supports a 5.5V output setting by shorting the RSEL pin to GND. However, selecting 5.4V or 5.5V disables Ultra-Low-Power Mode (ULPM), meaning the device will not operate below ~11mA load current in ULPM and will instead default to LPM/HPM. This reduces light-load efficiency slightly but retains full protection and regulation functionality - appropriate for applications prioritizing higher output voltage over sub-10μA quiescent performance.
What package options are available for the MAX17227AANT+T, and how do they differ electrically?
The MAX17227AANT+T is offered in two packages: a 6-bump WLP (1.58mm × 0.89mm) and an 8-pin TDFN (2mm × 2mm). Both share identical electrical specifications, including 2A peak current, 350nA IQ, and –40°C to +125°C operation. The WLP offers smallest footprint for space-constrained wearables; the TDFN provides better thermal dissipation (θJA = 85.3°C/W vs. 95.15°C/W) and includes dedicated AGND and EP pins for improved noise immunity in sensitive analog systems.
Does the MAX17227AANT+T provide short-circuit protection, and how does it behave during a fault?
Yes, the MAX17227AANT+T includes integrated short-circuit protection. When VOUT drops more than 1V below VIN, the device detects a short and disconnects the synchronous rectifier from the output. Input current is then limited to 1.1A (IIN_PT). Sustained short-circuit conditions cause power dissipation that triggers thermal shutdown at 165°C. After cooling by 15°C, the device auto-restarts - cycling on/off until the fault clears. No external components are needed for basic short-circuit defense.
