Product details
Overview
ADPL16000BATA+T from Analog Devices is a fixed 5.0V, 400mA synchronous step-down DC-DC converter with integrated MOSFETs, operating from 4.5V to 60V input. It delivers regulated power in ultra-compact industrial sensors and 4–20mA current loops, featuring internal compensation, 92% peak efficiency, and hiccup-mode overcurrent protection.
For engineers reviewing the ADPL16000BATA+T datasheet, ADPL16000BATA+T pinout, ADPL16000BATA+T application, or ADPL16000BATA+T equivalent, key selection criteria include its 5V fixed output, MODE-selectable PFM/PWM operation, open-drain RESET monitoring, programmable EN/UVLO threshold, and TDFN-CU 2mm × 2mm package compatibility with high-voltage point-of-load designs.
Technical Context
The ADPL16000BATA+T employs peak-current-mode control with a latched MODE pin that selects between constant-frequency PWM (MODE = GND) and light-load-optimized PFM (MODE unconnected). Its internal 5V LDO powers gate drivers and logic, with VCC dropout of 0.30V max at 5mA.
It integrates high-side pMOS (RDS-ONH = 1.8Ω typ @ +25°C) and low-side nMOS (RDS-ONL = 0.62Ω typ @ +25°C), enabling full-load efficiency without external Schottky diodes. Built-in soft-start (4.1ms), monotonic prebias startup, and 93.5–97.5% RESET trip thresholds ensure robust system-level power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 60V - supports direct connection to industrial 24V/48V rails and battery-backed systems without pre-regulation. |
| Output Voltage | Fixed 5.00V ±1.4% - tightly regulated for USB-peripheral, microcontroller I/O, and analog sensor biasing. |
| Max Output Current | 400mA - sufficient for dual-rail MCU cores, isolated ADCs, and low-power wireless transceivers. |
| Peak Efficiency | 92% - achieved using synchronous rectification and all-ceramic capacitor design, minimizing thermal load. |
| Shutdown Current | 2.2µA typical - enables long-term battery operation in remote sensing nodes. |
| Switching Frequency | 500kHz ±7% - balances EMI performance and inductor size; supports compact 68µH shielded inductors. |
| Operating Temp Range | −40°C to +125°C ambient - qualified for harsh industrial environments including HVAC and motor control enclosures. |
Pinout & Package
ADPL16000BATA+T is housed in an 8-pin, 2mm × 2mm TDFN-CU package with exposed thermal pad (pin 7 GND connected to pad). The package supports high thermal conductivity and minimal PCB footprint for space-constrained modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power Input | Accepts 4.5V–60V input; requires local 1µF X7R ceramic bypass to GND for stability and EMI suppression. |
| EN/UVLO (Pin 2) | Enable / Input UVLO Control | Active-high enable with 1.215V rising threshold; resistor divider enables programmable turn-on voltage (e.g., 12V or 24V system brownout detection). |
| VCC (Pin 3) | Internal LDO Output | 5.0V ±5% regulated supply for internal circuitry; must be bypassed with ≥1µF ceramic capacitor to GND. |
| FB/VOUT (Pin 4) | Feedback Input | Direct connection to 5V output for fixed-version regulation; no external resistors required - simplifies layout and reduces BOM count. |
| MODE (Pin 5) | PFM/PWM Selection | Ground for forced-PWM (fixed frequency); floating for automatic PFM at light loads - enables dynamic efficiency optimization. |
| RESET (Pin 6) | Open-Drain Reset Monitor | Pulls low when VOUT drops below 92% of 5V (4.6V); high-impedance after 2ms delay when VOUT rises above 95% (4.75V) - supports system-level fault recovery. |
| GND (Pin 7) | Power Ground | Primary ground reference for switching node, feedback, and thermal pad; must connect to solid ground plane for EMI and thermal performance. |
| LX (Pin 8) | Switch Node | Connects to inductor's switched side; carries high dv/dt pulses - requires tight loop routing and minimized trace area to reduce radiated emissions. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Synchronous MOSFETs | Eliminates external Schottky diode and reduces conduction loss - improves full-load efficiency and eases thermal design. |
| Internal Compensation & Soft-Start | Removes need for external compensation network and guarantees monotonic 4.1ms startup into prebiased outputs - prevents bus contention in multi-rail systems. |
| Programmable EN/UVLO Threshold | Enables system-level undervoltage lockout tuning (e.g., disable at VIN < 18V for 24V nominal systems) without additional comparators or resistors. |
| Hiccup-Mode Overcurrent Protection | Triggers after single runaway current event (>0.75A) or sustained output undervoltage (<65% of 5V), limiting fault energy and enabling self-recovery. |
| CISPR32 Class B Compliance | Meets conducted and radiated emission limits without external filters - reduces certification risk and board-level EMI debugging time. |

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 |
|---|---|---|---|
| LM5164QWRGRRQ1 | 4.5V–65V input, adjustable output, 400mA, requires external compensation and feedback resistors. | Supports variable output voltages but adds BOM cost and layout complexity for fixed 5V use. | Choose if adjustable output or AEC-Q100 qualification is required; not drop-in for ADPL16000BATA+T's fixed 5V configuration. |
| TPS54340DDAR | 3.5V–42V input, adjustable output, 3.5A capability, external MOSFETs, no integrated LDO or RESET. | Higher current capacity but lacks built-in reset monitoring, VCC LDO, and PFM mode - increases system component count. | Prefer for higher-current designs where external FETs and flexibility outweigh integration benefits of ADPL16000BATA+T. |
Compared with LM5164QWRGRRQ1 and TPS54340DDAR, ADPL16000BATA+T offers plug-and-play 5V regulation with integrated RESET, VCC LDO, and PFM/PWM mode selection - reducing bill-of-materials, layout area, and qualification effort for fixed-output industrial point-of-load applications.

FAQ
What output voltage does the ADPL16000BATA+T deliver?
The ADPL16000BATA+T delivers a fixed 5.00V output with ±1.4% regulation over temperature and load. Its FB/VOUT pin connects directly to the output - no external feedback resistors are needed. This simplifies design and improves accuracy compared to adjustable converters requiring precision resistor networks.
Does the ADPL16000BATA+T support both PWM and PFM modes?
Yes, the ADPL16000BATA+T supports both modes via the MODE pin: grounding MODE forces constant-frequency PWM operation, while leaving it unconnected enables automatic PFM at light loads. This dual-mode capability ensures high efficiency across full load range - 92% peak in PWM and >85% at 1mA in PFM.
How does the RESET pin function on the ADPL16000BATA+T?
The ADPL16000BATA+T RESET pin is an open-drain output that pulls low when VOUT falls below 92% of 5V (4.6V) and goes high-impedance 2ms after VOUT rises above 95% (4.75V). It asserts low during hiccup-mode faults, providing reliable power-good signaling for microcontrollers and FPGA configuration sequencers.
What is the thermal performance of the ADPL16000BATA+T in its TDFN-CU package?
The ADPL16000BATA+T in its 2mm × 2mm TDFN-CU package has a thermal resistance θJA of 202°C/W and supports continuous operation up to +125°C ambient. With 496mW max power dissipation at +70°C and derating of 6.2mW/°C above, it sustains 400mA at 5V output even in enclosed industrial enclosures without forced airflow.
Can the ADPL16000BATA+T start up into a prebiased output?
Yes, the ADPL16000BATA+T supports monotonic startup into prebiased outputs in both PFM and PWM modes. Its internal soft-start circuit ramps the error amplifier reference without discharging the output capacitor - critical for powering multi-rail systems where other supplies may already be active.
