Product details
Overview
MAX17570BATA+T from Analog Devices is a 4.5V–60V input, 5V fixed-output, 300mA synchronous step-down DC-DC converter in an ultra-compact 2mm × 2mm TDFN package. It integrates high-side pMOS and low-side nMOS FETs (RDS-ONH = 2.76Ω max, RDS-ONL = 1Ω max), delivers 95.8% peak efficiency at 15VIN/12VOUT/150mA, and features hiccup-mode current limit, open-drain RESET, and -40°C to +125°C ambient operation - deployed in factory automation power rails where thermal management and small footprint are critical.
For engineers reviewing the MAX17570BATA+T datasheet, MAX17570BATA+T pinout, MAX17570BATA+T application, or MAX17570BATA+T equivalent, key selection considerations include its 5V fixed output (±1.4% regulation), programmable EN/UVLO threshold (1.215V typ rising), 200kHz–1MHz adjustable switching frequency, PFM/PWM mode compatibility, and compliance with CISPR32 Class B emissions - all within a thermally robust 8-pin TDFN package.
Technical Context
The MAX17570BATA+T implements a current-mode, internally compensated PWM control architecture with monotonic soft-start (512 cycles) and built-in slope compensation. Its dual-MOSFET topology eliminates external Schottky diodes, while the integrated 5V LDO (VCC) powers internal logic and gate drivers with 4.75V–5.25V output and 13–50mA current limit.
It supports reliable startup into prebiased outputs and includes comprehensive protection: cycle-by-cycle peak current limit (0.56A typ), runaway current limit (0.66A typ), thermal shutdown (166°C, 20°C hysteresis), and open-drain RESET with 95% rising / 92% falling thresholds - all operating across industrial temperature extremes and meeting conducted/radiated EMI requirements per CISPR32 Class B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 60V - enables direct connection to unregulated industrial or automotive battery rails without pre-regulation. |
| Output Voltage | Fixed 5.0V ±1.4% - eliminates external feedback resistors and simplifies layout for stable 5V point-of-load systems. |
| Max Output Current | 300mA - sufficient for powering microcontrollers, sensors, and interface ICs in space-constrained embedded designs. |
| Peak Efficiency | 95.8% at VIN=15V, VOUT=12V, IOUT=150mA - minimizes thermal dissipation and extends system uptime in sealed enclosures. |
| Shutdown Current | 2.2μA (typ) - preserves battery life in always-on monitoring applications such as asset trackers. |
| Switching Frequency | 200kHz to 1MHz (adjustable via RT resistor or external SYNC clock) - allows EMI optimization and inductor size reduction. |
| Operating Temp | -40°C to +125°C ambient - certified for deployment in harsh industrial environments including motor control cabinets and PLC backplanes. |
Pinout & Package
Package: 8-pin, 2mm × 2mm TDFN (Package Code T822C+6C), exposed pad for thermal enhancement. Thermal resistance θJA = 162°C/W (4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power Input | Primary input supply rail; requires local 1μF X7R ceramic bypass to GND for noise suppression and transient response. |
| EN/UVLO (Pin 2) | Enable & Input UVLO Input | Active-high enable with programmable turn-on threshold (1.215V typ); supports resistor-divider-based input undervoltage lockout. |
| VCC (Pin 3) | LDO Output | Internally regulated 5V supply for gate drivers and control circuitry; must be bypassed with ≥1μF capacitor to GND. |
| VOUT/FB (Pin 4) | Feedback Input | Connects directly to 5V output for fixed-voltage operation; monitors regulation accuracy and triggers RESET assertion. |
| RT/SYNC (Pin 5) | Oscillator Timing / Sync Input | Resistor-programmable frequency (200kHz–1MHz); supports external clock synchronization for noise-sensitive multi-rail systems. |
| RESET (Pin 6) | Open-Drain Reset Output | Asserts low when VOUT falls below 92% of nominal; releases after 1024 cycles once VOUT exceeds 95% - enables system-level power sequencing. |
| GND (Pin 7) | Power Ground | Common return path for VIN, VCC, and LX; must connect to low-impedance ground plane at single-point star node. |
| LX (Pin 8) | Switch Node | Connection to inductor switch node; carries high dv/dt pulses; requires short, low-inductance trace to minimize EMI and ringing. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous Rectification | Integrated high-side pMOS and low-side nMOS eliminate external Schottky losses and improve light-load efficiency. |
| Internal Compensation | Reduces BOM count by removing external compensation network - accelerates design cycle and improves stability margin. |
| All-Ceramic Capacitor Support | Enables fully ceramic input/output filtering (no electrolytics), reducing solution size and improving reliability over temperature. |
| Monotonic Prebias Startup | Starts cleanly into existing output voltage without discharging downstream capacitors - essential for multi-rail SoC power sequencing. |
| Hiccup-Mode Overcurrent Protection | Enters low-power retry mode during sustained overload or short-circuit, limiting junction temperature rise and enabling self-recovery. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QWRGTRQ1 | Automotive-grade AEC-Q100 qualified; 3.5V–65V input; 300mA; adjustable output only; no fixed 5V option. | Targeted for automotive infotainment and ADAS subsystems requiring qualification - not drop-in for industrial fixed-VOUT use. | Select if AEC-Q100 compliance and extended temp range (+150°C junction) are mandatory; redesign required for feedback network and layout. |
| TPS54202DRCT | 2.9V–60V input; 2A output; 5V fixed option available; requires external compensation; larger 10-pin WSON package. | Better suited for higher-current loads (>300mA); less compact; lacks hiccup-mode and CISPR32 Class B compliance. | Choose when output current demand exceeds 300mA or when cost sensitivity outweighs size/EMI requirements. |
Compared with LM5164QWRGTRQ1 and TPS54202DRCT, the MAX17570BATA+T provides a uniquely optimized balance of fixed 5V output, ultra-small 2mm × 2mm footprint, integrated protection, and Class B EMI compliance - making it ideal for space-constrained industrial and aftermarket applications where reliability and regulatory readiness are non-negotiable.

FAQ
What output voltage does the MAX17570BATA+T deliver?
The MAX17570BATA+T delivers a fixed 5.0V output with ±1.4% regulation accuracy over line, load, and temperature. This is achieved via internal feedback resistors - no external divider is needed. The device's VOUT/FB pin connects directly to the output, and its regulation voltage is specified as 4.93V to 5.07V at TA = +25°C, with full-range performance validated from -40°C to +125°C ambient.
Does the MAX17570BATA+T support external frequency synchronization?
Yes, the MAX17570BATA+T supports external clock synchronization via the RT/SYNC pin - but only in PWM-mode variants (MAX17570A/B/C). As a MAX17570B variant, it operates in PWM mode across all loads and fully supports SYNC functionality. The external clock must fall within 1.1× to 1.4× the programmed switching frequency, with pulse width >100ns and duty cycle between 10% and 90%.
What protection features are integrated into the MAX17570BATA+T?
The MAX17570BATA+T integrates multiple hardware-based protections: cycle-by-cycle peak current limit (0.56A typ), runaway current limit (0.66A typ), hiccup-mode recovery, open-drain RESET with 95%/92% thresholds, monotonic prebias startup, programmable EN/UVLO, overtemperature shutdown (166°C, 20°C hysteresis), and VCC UVLO (3.8V falling). These operate autonomously without software intervention.
Can the MAX17570BATA+T operate with ceramic capacitors only?
Yes, the MAX17570BATA+T is explicitly designed for all-ceramic capacitor operation. Its internal compensation and current-mode control ensure stability with low-ESR X7R ceramic input (≥1μF) and output (calculated per application) capacitors - eliminating the need for bulk electrolytics and reducing solution size, cost, and aging-related failure modes.
What is the thermal performance of the MAX17570BATA+T in a standard PCB layout?
In a 4-layer JEDEC-standard board, the MAX17570BATA+T exhibits θJA = 162°C/W and θJC = 20°C/W. At 300mA load and 24VIN/5VOUT, typical power dissipation is ~180mW, resulting in ~29°C junction-to-ambient rise above board temperature. The exposed pad must be soldered to a thermal copper pour for optimal performance; derating begins above +70°C ambient (6.2mW/°C).
