Product details
Overview
MAX15062BATA+T from Analog Devices is a 60V-input, 5V-output synchronous step-down DC-DC converter with integrated high-side pMOS and low-side nMOS FETs, delivering up to 300mA output current, operating from -40°C to +125°C ambient, and housed in an 8-pin 2mm × 2mm TDFN package. It supports configurable PFM/PWM mode selection via the MODE pin and includes internal soft-start, open-drain RESET monitoring, and programmable EN/UVLO for industrial point-of-load regulation.
For engineers reviewing the MAX15062BATA+T datasheet, MAX15062BATA+T pinout, MAX15062BATA+T application, or MAX15062BATA+T equivalent, key selection considerations include its 4.5V–60V wide input range, fixed 5V output with ±1.4% regulation accuracy over temperature, peak efficiency of 92%, 2.2µA shutdown current, and hiccup-mode current limiting for robust operation in 4–20mA loops and process control systems.
Technical Context
The MAX15062BATA+T implements peak-current-mode control with internal slope compensation and a latched MODE pin that determines startup behavior: grounded MODE enables forced-PWM (constant 500kHz switching), while unconnected MODE enables light-load PFM with pulse-skipping and zero negative inductor current. Its error amplifier compares FB/VOUT voltage against a 0.9V internal reference, and the integrated 5V LDO (VCC) powers internal circuitry with 150mV dropout at 5mA.
Protection features include monotonic startup into prebiased outputs, hiccup-mode current limit triggered after one runaway cycle, thermal shutdown at 166°C with 10°C hysteresis, and output voltage monitoring via RESET with 92% falling / 95% rising thresholds and 2ms delay. The device sustains continuous short-circuit operation and supports all-ceramic capacitor designs with no external compensation required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 60V - Enables direct replacement of high-voltage LDOs and compatibility with 24V/48V industrial bus rails. |
| Output Voltage | Fixed 5.0V ±1.4% - Guaranteed regulation across -40°C to +125°C ambient without external feedback resistors. |
| Max Output Current | 300mA - Sufficient for powering microcontrollers, sensors, and analog front-ends in space-constrained industrial modules. |
| Peak Efficiency | 92% at 24VIN/5VOUT/300mA - Minimizes thermal stress and eliminates need for heatsinking in sealed enclosures. |
| Switching Frequency | 465kHz to 535kHz - Fixed-frequency PWM operation avoids EMI band interference; PFM mode skips cycles below ~55mA load. |
| Shutdown Current | 2.2µA (typ) - Enables ultra-low-power sleep modes in battery-backed or energy-harvesting systems. |
| Soft-Start Time | 4.1ms (typ) - Prevents inrush current and ensures monotonic VOUT ramp even into prebiased loads. |
Pinout & Package
Package: 8-pin TDFN (2mm × 2mm, 0.5mm pitch), thermally enhanced with exposed pad (pin 7 = GND). RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power Input | Primary input rail connection; requires local 1µF X7R ceramic bypass to GND to suppress high-frequency noise and support transient response. |
| EN/UVLO (Pin 2) | Enable & Input UVLO Control | Active-high logic input; rising threshold 1.215V enables startup; resistor divider from VIN allows programmable turn-on voltage (e.g., 12V system enable at 10.8V). |
| VCC (Pin 3) | Internal LDO Output | 5V regulated supply for internal circuitry; must be bypassed with ≥1µF ceramic capacitor to GND to maintain stability and reduce ripple. |
| FB/VOUT (Pin 4) | Feedback Input | Direct connection to 5V output for fixed-version operation; no external resistors needed-internal divider sets regulation at 0.9V reference. |
| MODE (Pin 5) | Control Mode Selection | Latched at power-up: GND = forced-PWM (constant frequency); floating = PFM (pulse-skipping, higher light-load efficiency). |
| RESET (Pin 6) | Open-Drain Fault Monitor | Pulls low when VOUT drops below 92% of nominal; high-impedance 2ms after VOUT exceeds 95%; requires external pull-up resistor. |
| GND (Pin 7) | Power & Signal Ground | Common return path for VIN, VCC, FB/VOUT, and LX; must connect to low-impedance ground plane and tie all GND nodes at single point. |
| LX (Pin 8) | Switch Node | Connection to inductor switch node; high-impedance during shutdown; carries high di/dt - requires short, wide trace and minimized loop area. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous MOSFET Integration | Eliminates external Schottky diode and reduces conduction losses - high-side RDS(on) = 1.75Ω, low-side RDS(on) = 0.55Ω at +25°C. |
| Internal Compensation | Removes need for external Type-II/III compensation network - simplifies layout and reduces BOM count in space-constrained designs. |
| Programmable EN/UVLO Threshold | Enables precise brown-in/brown-out control using two external resistors - supports reliable startup in fluctuating 24V/48V industrial supplies. |
| Hiccup-Mode Overcurrent Protection | Disables switching and retries after 131ms timeout upon runaway current detection - prevents thermal runaway during sustained overload or short-circuit. |
| Monotonic Prebias Startup | Allows safe power-up into existing output voltage without discharging downstream capacitors - critical for multi-rail FPGA or MCU systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QWRGRRQ1 | 4.5V–65V input, 5V fixed output, 300mA, AEC-Q100 qualified; requires external compensation and feedback resistors. | Automotive-grade qualification; lacks integrated feedback divider and RESET output. | Select for automotive under-hood applications requiring ASIL-B compliance; not drop-in due to different pinout and external components. |
| TPS54340DDAR | 3.5V–42V input, adjustable output, 3.5A capability; external MOSFETs, no integrated LDO, no RESET pin. | Higher current capacity but larger solution size; no built-in 5V fixed option or output monitoring. | Choose when >300mA load or wider output adjustability is needed; requires redesign of feedback and protection circuitry. |
Compared with LM5164QWRGRRQ1 and TPS54340DDAR, the MAX15062BATA+T provides a smaller footprint, lower component count (no external resistors or compensation), and integrated RESET monitoring - making it optimal for cost-sensitive, space-constrained industrial point-of-load designs where 300mA and fixed 5V are sufficient.

FAQ
What is the output voltage tolerance of the MAX15062BATA+T over temperature and load?
The MAX15062BATA+T delivers a fixed 5.0V output with ±1.4% regulation accuracy across -40°C to +125°C ambient temperature and full 0–300mA load range. This is verified by the Electrical Characteristics table showing VOUT-REG minimum of 4.93V and maximum of 5.18V under specified test conditions, ensuring stable operation in uncontrolled industrial environments.
Does the MAX15062BATA+T require external compensation components?
No, the MAX15062BATA+T features internal compensation and does not require external Type-II or Type-III compensation networks. Its peak-current-mode architecture with built-in slope compensation and optimized error amplifier response eliminates the need for external capacitors or resistors on the COMP pin - reducing BOM count and PCB area.
How does the MODE pin affect efficiency and EMI performance in the MAX15062BATA+T?
When the MODE pin is left unconnected, the MAX15062BATA+T operates in PFM mode, skipping pulses at light loads (<55mA) to achieve >85% efficiency down to 1mA - ideal for low-power sensor nodes. When MODE is grounded, it forces constant-frequency PWM operation (≈500kHz), providing predictable EMI spectrum and immunity to frequency-sensitive circuits, though light-load efficiency drops to ~70%.
Can the MAX15062BATA+T safely start up into a prebiased output voltage?
Yes, the MAX15062BATA+T supports monotonic startup into a prebiased output without discharging the output capacitor - confirmed in the Detailed Description section. This feature prevents voltage reversal and data corruption in multi-rail systems where 5V may already be present from another supply before the MAX15062BATA+T is enabled.
What protection features are integrated into the MAX15062BATA+T?
The MAX15062BATA+T integrates hiccup-mode overcurrent protection (triggered after one runaway cycle, then 131ms timeout), thermal shutdown at 166°C with 10°C hysteresis, output undervoltage monitoring via open-drain RESET pin (92% trip, 95% release), and EN/UVLO with programmable thresholds - collectively enabling robust operation in industrial settings with variable input and load conditions.
