Product details
Overview
MAX17227JATA+T from Analog Devices is a nanoPower synchronous boost converter IC designed for ultra-low-power battery systems. It delivers up to 500mA peak inductor current, operates from 400mV–5.5V input, regulates output from 2.3V–5.4V (via single RSEL resistor), achieves 95% peak efficiency and 350nA quiescent supply current, and supports automatic pass-through mode for direct input-to-output conduction - ideal for wearable medical sensors and low-duty-cycle IoT nodes.
For engineers reviewing the MAX17227JATA+T datasheet, MAX17227JATA+T pinout, MAX17227JATA+T application, or MAX17227JATA+T equivalent, key selection criteria include its 350nA IQ, 880mV startup voltage, True Shutdown™ with active discharge, adaptive on-time PFM control, and dual-package availability (6-bump WLP or 8-pin TDFN) for space-constrained designs.
Technical Context
The MAX17227JATA+T implements an adaptive on-time pulse-frequency-modulation (PFM) control scheme that dynamically shifts between ultra-low-power mode (ULPM), low-power mode (LPM), and high-power mode (HPM) based on load current - enabling 90% efficiency at 10μA and 89% at 500μA. Its cycle-by-cycle inductor current limit is fixed at 500mA, and it features integrated high-side (280mΩ RDS(ON)) and low-side (160mΩ RDS(ON)) FETs with internal gate drive.
True Shutdown™ disconnects OUT from IN with zero forward/reverse leakage, while the active discharge resistor (225–900Ω) safely drains the output capacitor. Automatic pass-through activates when VIN > VOUT + 0.4V, using a dedicated 650mΩ RDS(ON) switch rated for 1A continuous conduction - all with short-circuit and thermal shutdown protection active even in shutdown.
Key Specifications

| Input Voltage Range | 400mV to 5.5V - supports single-cell Li-SOCl₂, alkaline, or NiMH down to near-dead state |
| Output Voltage Range | 2.3V to 5.4V in 100mV steps - set by single external resistor (RSEL), no feedback divider needed |
| Peak Inductor Current Limit | 500mA - cycle-by-cycle protected; defines max deliverable power at given VIN/VOUT |
| Startup Input Voltage | 880mV @ 3kΩ load - allows cold-start from weak or partially discharged batteries |

Pinout & Package
MAX17227JATA+T is available in two packages: 1.58mm × 0.89mm, 6-bump WLP (3×2, 0.4mm pitch) and 2mm × 2mm, 8-pin TDFN. The TDFN variant (indicated by "T" suffix) includes separate AGND and GND pins plus exposed pad (EP) for thermal management. Both packages support the same pin functions and electrical behavior.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input Power Supply | Accepts 400mV–5.5V; connects to input capacitor (min 10μF) and inductor |
| OUT | Regulated Output | Delivers 2.3V–5.4V; requires 10μF X7R ceramic capacitor to ground |
| LX | Switching Node | Connects to inductor; internal high/low-side FETs switch here; clamped to GND/OUT |
| GND | Power Ground | Primary return path for input/output currents; ties to PCB ground plane |
| AGND | Analog Ground | Reference for internal error amplifier and RSEL detection; must connect to EP externally |
| RSEL | Output Voltage Select | Single resistor to GND sets VOUT; <2pF capacitance required for accurate detection |
| EN | Enable Control | Logic-high (>0.95V) enables regulation; logic-low (<0.55V) enters True Shutdown™ |
| EP | Exposed Thermal Pad | Internally connected to AGND; must be soldered to PCB ground for thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| True Shutdown™ with active discharge | Zero reverse current + 225–900Ω discharge path ensures safe, rapid VOUT collapse during disable |
| Adaptive on-time PFM control | Enables ULPM/LPM/HPM transitions without external compensation - maintains stability across 6-decade load |
| Automatic pass-through mode | Engages when VIN > VOUT + 0.4V; uses dedicated 650mΩ switch to bypass regulation loss |
| Single-resistor output programming | Eliminates feedback divider; reduces BOM count, board area, and light-load current draw vs. conventional solutions |
| Integrated protection suite | Short-circuit, overtemperature, and cycle-by-cycle current limiting remain active in all operating modes including shutdown |
Applications
| Clinical Sensor Node | Emergency Lighting Backup |
|---|---|

IC Role / Device Role / Timing Role: Ultra-low-IQ regulator powering analog front-end and MCU, entering ULPM during 99% of idle time. Use Value: ULPM delivers 90% efficiency at 10μA, enabling 2-week runtime on 100mAh microbattery; active discharge prevents residual VOUT after shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar nanoPower boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61291DRVR | Higher IQ (600nA), no pass-through mode, fixed 3.3V/5.0V outputs only, no RSEL programmability | Suitable for simpler fixed-voltage designs where pass-through efficiency gain is unnecessary | Choose if design requires only standard voltages and can tolerate higher IQ; avoid if variable VOUT or pass-through is needed |
| MAX17222GTA+T | Same family, lower peak current (300mA), identical IQ (350nA), same RSEL programming and pass-through capability | Better suited for sub-200mA loads where smaller inductor and reduced thermal stress are priorities | Select when load current stays below 300mA - offers identical feature set with lower current rating and potentially smaller solution size |
Compared with TPS61291DRVR and MAX17222GTA+T, the MAX17227JATA+T uniquely combines 500mA peak current, programmable output via RSEL, and automatic pass-through - making it optimal for variable-load, battery-critical systems needing both flexibility and efficiency across wide VIN ranges.

FAQ
What is the minimum input voltage required for MAX17227JATA+T to start up?
The MAX17227JATA+T starts up with an input voltage as low as 880mV when loaded with ≥3kΩ. This enables reliable operation from deeply discharged primary cells. Below this threshold, the device remains inactive. Once started, it continues regulating down to 400mV input - critical for maximizing usable battery capacity in MAX17227JATA+T-based systems.
How does the RSEL pin configure the output voltage on MAX17227JATA+T?
The RSEL pin on MAX17227JATA+T accepts a single resistor to ground to select one of 31 output voltages from 2.3V to 5.4V in 100mV steps. During startup, the IC sources ~200μA for ~600μs to read the resistance value. Capacitance on RSEL must stay under 2pF. This method eliminates feedback dividers, reducing cost, size, and light-load current - a defining feature of the MAX17227JATA+T.
Does MAX17227JATA+T support true shutdown with zero leakage current?
Yes. MAX17227JATA+T features True Shutdown™, a proprietary mode where both forward and reverse current paths between IN and OUT are fully disconnected. Input shutdown current is specified at just 1nA typical. Additionally, an internal active discharge resistor (225–900Ω) pulls the output capacitor to ground upon shutdown - ensuring safe, rapid VOUT collapse in MAX17227JATA+T applications.
What protection features are active in shutdown mode for MAX17227JATA+T?
In True Shutdown™ mode, MAX17227JATA+T maintains short-circuit protection and thermal shutdown functionality - meaning if a fault occurs while disabled (e.g., output shorted), the device remains protected and will not latch or sustain damage. This is distinct from many boost converters whose protections deactivate in shutdown. The MAX17227JATA+T's robustness in all states enhances system reliability.
Can MAX17227JATA+T operate in automatic pass-through mode, and what triggers it?
Yes. MAX17227JATA+T automatically enters pass-through mode when VIN exceeds VOUT by ≥0.4V. It then uses a dedicated low-RDS(ON) (650mΩ) internal switch to directly connect IN to OUT, bypassing switching losses. This mode supports up to 1A continuous current and retains short-circuit and thermal protection - a key efficiency advantage for MAX17227JATA+T in battery-supplied systems with variable input voltage.
