Product details
Overview
ADPL26001ES6#TRPBF from Analog Devices is a current-mode DC/DC converter IC capable of boost, SEPIC, or inverting topologies with a 1A, 60V internal power switch, 3.2V–36V input range, 2MHz fixed switching frequency, and 6µA quiescent current in Burst Mode-designed for space-constrained industrial and portable electronics requiring regulated positive or negative output voltages.
For engineers reviewing the ADPL26001ES6#TRPBF datasheet, ADPL26001ES6#TRPBF pinout, ADPL26001ES6#TRPBF application, or ADPL26001ES6#TRPBF equivalent, key selection criteria include its dual-polarity feedback architecture (1.6V for positive / –0.8V for negative outputs), EN/UVLO threshold accuracy (±20mV), internal compensation, soft-start timing (1ms), and thermal lockout at 170°C junction temperature.
Technical Context
The ADPL26001ES6#TRPBF implements a fixed-frequency (2MHz) current-mode control architecture with dual error amplifiers-one active for boost/SEPIC (FBX referenced to 1.6V), the other for inverting mode (FBX referenced to –0.8V). Its VC node servo loop adjusts peak switch current based on FBX deviation from the selected reference.
It integrates frequency foldback during start-up or fault conditions to prevent inductor current runaway when duty cycle approaches minimum on-time limits (70ns typ), and includes thermal lockout (TJ > 170°C) that resets soft-start and pulls down VC-ensuring safe recovery after overtemperature events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.2V to 36V - supports wide-input industrial rails and automotive battery-supplied systems without pre-regulation. |
| Quiescent Current (Burst Mode) | 6µA - enables multi-year battery life in always-on IoT sensors and portable medical devices. |
| Switch Rating | 1A, 60V - handles high-voltage boost (e.g., 12V→48V) and robust SEPIC/inverting operation with margin against transients. |
| Feedback Reference | 1.6V (positive VOUT) or –0.8V (negative VOUT) - single-pin topology selection eliminates external mode-switching logic. |
| Switching Frequency | 2MHz (±10%) - allows use of sub-2.2µH inductors and compact 0603/0805 ceramic capacitors for minimal PCB area. |
| EN/UVLO Threshold | 1.60V (falling), 1.68V (rising) - 80mV hysteresis prevents chatter during brown-out; enables precise system-level input voltage programming. |
| Soft-Start Time | 1ms - limits inrush current into output capacitors, preventing diode stress and input rail sag during cold start. |
Pinout & Package
ADPL26001ES6#TRPBF is packaged in a 6-lead TSOT-23 (S6) package with 1mm profile, optimized for thermal performance via exposed pad grounding in DFN variants-this S6 variant uses standard leadframe layout without exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input Supply Rail | Must be bypassed locally with ≥10µF ceramic capacitor; connects directly to internal LDO (INTVCC) and switch driver supply. |
| INTVCC | Internally Regulated 3V Supply | Output of VIN-fed LDO; requires ≥1µF low-ESR ceramic cap to ground-no external loading permitted. |
| EN/UVLO | Enable & Undervoltage Lockout Input | Logic-controlled shutdown pin with accurate 1.60V/1.68V thresholds; draws <1µA below 0.2V for ultra-low standby power. |
| SW | Switch Node | Drives external inductor/diode; high dv/dt node-requires minimized trace area and tight layout to reduce EMI. |
| GND | Power & Signal Ground | Primary return path for switch current and internal circuitry; must connect to low-impedance PCB ground plane. |
| FBX | Topology-Selectable Feedback Input | Sets output regulation point: 1.6V for positive VOUT (boost/SEPIC), –0.8V for negative VOUT (inverting); bias current <10nA. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Polarity Feedback Architecture | Single FBX pin supports both 1.6V-referenced positive outputs and –0.8V-referenced negative outputs-eliminates need for external topology-select logic or dual feedback networks. |
| Low-Ripple Burst Mode | Maintains output ripple <15mV while drawing only 6µA IQ-enables stable regulation across 1000:1 load range without external sleep-mode controllers. |
| Internal Compensation | Eliminates external compensation components-reduces BOM count and layout sensitivity while ensuring stability across full input/output operating range. |
| Frequency Foldback | Reduces switching frequency during start-up or fault conditions to maintain control when duty cycle approaches minimum on-time limit (70ns), preventing inductor saturation. |
| Thermal Lockout Protection | Halts switching and resets soft-start when junction temperature exceeds 170°C-prevents thermal runaway and enables safe auto-recovery after cooling. |
Applications
| Industrial Sensor Transmitters | Portable Medical Diagnostics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DC/DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT3958EMS#TRPBF | Higher 3.3A switch rating, 100V max SW, no integrated soft-start or frequency foldback; requires external compensation. | Better suited for high-current boost (≥500mA) or 48V telecom applications; lacks ultra-low-IQ Burst Mode. | Select LT3958EMS#TRPBF only when >1A output current or >60V transient tolerance is required-sacrifices 6µA IQ and internal compensation. |
| TPS61088RHLR | 10V max SW, 4.5A switch, 500kHz–2.2MHz adjustable frequency, no negative output capability, higher 25µA IQ. | Optimized for high-efficiency single-cell to 5V/12V boost; cannot generate negative rails or support 36V inputs. | Choose TPS61088RHLR for cost-sensitive consumer applications needing >2A at ≤12V output-avoid where bipolar supplies or wide VIN are mandatory. |
Compared with LT3958EMS#TRPBF and TPS61088RHLR, ADPL26001ES6#TRPBF uniquely combines ultra-low 6µA quiescent current, dual-polarity output capability, internal compensation, and 60V switch rating in a 6-lead TSOT-making it optimal for space- and power-constrained industrial and portable systems requiring flexible topology selection.

FAQ
What topologies does the ADPL26001ES6#TRPBF support, and how is topology selected?
The ADPL26001ES6#TRPBF supports boost, SEPIC, and inverting configurations-all selectable via the FBX feedback network alone. When FBX is biased above GND (e.g., resistor divider from positive VOUT to GND), it regulates to 1.6V for boost/SEPIC. When FBX is biased below GND (e.g., divider from negative VOUT to GND), it regulates to –0.8V for inverting operation. No external mode pins or configuration registers are needed-topology is purely analog-defined by the external resistor network connected to FBX.
Does the ADPL26001ES6#TRPBF require external compensation components?
No, the ADPL26001ES6#TRPBF features fully internal compensation. Its current-mode architecture with integrated error amplifier and slope compensation eliminates the need for external Type-II or Type-III compensation networks. This reduces BOM count, simplifies layout, and guarantees stability across the full operating range (3.2V–36V VIN, –15V to +48V VOUT) without tuning.
What is the maximum output current achievable with the ADPL26001ES6#TRPBF in boost configuration?
In boost configuration, the ADPL26001ES6#TRPBF delivers up to 300mA at +48V output from a 12V input (typical), limited by its 1A switch current rating, thermal dissipation in the TSOT-23 package, and inductor saturation current. Peak switch current is clamped at 1.2A (typ), and practical continuous output depends on layout, ambient temperature, and inductor DCR-designs exceeding 250mA require careful thermal management and low-DCR inductors.
How does the EN/UVLO pin function on the ADPL26001ES6#TRPBF, and can it be used for system-level brown-out protection?
The EN/UVLO pin on the ADPL26001ES6#TRPBF provides precise enable control and programmable undervoltage lockout. With a rising threshold of 1.68V (±20mV) and falling threshold of 1.60V (±20mV), it offers 80mV hysteresis to prevent oscillation during brown-out. By resistively dividing the system input rail to this pin, designers can set custom turn-on/turn-off voltages-for example, enabling at 9V and disabling at 8.5V-making it ideal for automotive cold-crank and industrial brown-out protection.
Is the ADPL26001ES6#TRPBF pin-compatible with other members of the ADPL2600x family?
No, the ADPL26001ES6#TRPBF is not pin-compatible with other ADPL2600x variants such as the DFN-packaged ADPL26001EDDB#TRPBF. While both share identical electrical functionality and pin functions, the TSOT-23 (S6) package has 6 leads with different pinout order (VIN, INTVCC, EN/UVLO, SW, GND, FBX), whereas the DFN (DDB) package has 8 leads plus exposed thermal pad (Pin 9 = GND) and includes an NC pin. PCB layout and footprint must be specific to the S6 package.
