Product details
Overview
TPS62841YBGR from Texas Instruments is a synchronous step-down DC/DC converter optimized for ultra-low-power battery-operated systems, featuring 60-nA typical quiescent current, 750-mA output capability, 1.8-V to 6.5-V input range, and 16 selectable output voltages (0.8 V to 1.55 V in 50-mV steps) via external RSET resistor - deployed in wearable medical sensors and NB-IoT asset trackers.
For engineers reviewing the TPS62841YBGR datasheet, TPS62841YBGR pinout, TPS62841YBGR application, or TPS62841YBGR equivalent, key selection criteria include its WCSP-6 package footprint, STOP pin for noise-free measurement windows, DCS-Control™ topology for RF-friendly operation, and confirmed 120-nA IQ in 100% duty-cycle mode at end-of-battery discharge.
Technical Context
The TPS62841YBGR implements TI's DCS-Control™ architecture with dual-loop regulation: a fast AC loop sensing VOS for transient response and ripple suppression, plus a DC loop for precise load/line regulation. It supports seamless PFM/PWM transition and includes dedicated STOP functionality that halts switching while maintaining regulated output from CO charge.
This device integrates an R2D (resistor-to-digital) converter for VSET-based voltage selection, internal UVLO (1.72 V rising, 1.45 V falling), and thermal shutdown at 160°C with 5°C hysteresis. The WCSP-6 package lacks MODE and STOP pins - confirming fixed Power-Save Mode operation without forced-PWM capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8 V to 6.5 V - supports single-cell Li-ion, Li-SOCl₂, and 2–4S alkaline batteries. |
| Quiescent Current (IQ) | 60 nA typical - enables >10-year battery life in always-on sensor nodes drawing µA loads. |
| Output Current | 750 mA - sufficient for BLE/Wi-Fi coexistence in compact IoT edge devices. |
| Output Voltage Range | 0.8 V to 1.55 V in 50-mV steps - matches low-voltage MCU cores and RF transceivers. |
| Switching Frequency | 1.8 MHz nominal - allows use of small 2.2-µH inductors and 10-µF ceramic output capacitors. |
| Shutdown Current | 25 nA - ensures minimal leakage during deep sleep or system standby states. |
| Package | WCSP-6 (0.97 mm × 1.47 mm) - ultra-compact footprint for space-constrained wearables and patches. |
Pinout & Package
TPS62841YBGR uses a 6-pin Wafer Chip Scale Package (WCSP-YBG) with 0.97 mm × 1.47 mm body size and 0.4-mm pitch. Thermal performance is enhanced via direct die attach to PCB copper; no exposed pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power Input | Accepts 1.8–6.5 V; requires 4.7-µF ceramic capacitor placed adjacent for EMI suppression. |
| GND | Ground Reference | Common return for VIN, VOS, and SW; must be low-impedance connection to PCB ground plane. |
| SW | Switch Node | Connects to inductor; carries high di/dt switching current - routing must minimize loop area. |
| VSET | Voltage Selection Input | Resistor-to-GND sets output voltage via internal R2D converter; max parasitic capacitance = 100 pF. |
| VOS | Output Sense & Discharge | Direct connection to output capacitor; enables automatic VOUT discharge when EN = GND. |
| EN | Enable Control | Logic-high enables regulator; internal 450-kΩ pulldown prevents floating start-up; no MODE or STOP pins present. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ Topology | Enables <10 mV output ripple and sub-10 µs load transient recovery without external compensation. |
| 100% Duty-Cycle Mode | Extends runtime near battery depletion with only 120-nA IQ - critical for long-life coin-cell applications. |
| Output Discharge Function | Internal MOSFET sinks up to 44 mA through VOS pin to safely discharge VOUT during shutdown. |
| RF-Friendly Operation | No frequency dithering or spread-spectrum required - clean 1.8-MHz fundamental minimizes interference with 2.4-GHz radios. |
| UVLO Protection | Prevents erratic behavior below 1.45 V input; restarts cleanly above 1.72 V with full soft-start sequence. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62840YBG | Output range: 1.8–3.3 V (100-mV steps); same 60-nA IQ and WCSP-6 package. | Designed for higher-voltage MCUs and legacy 3.3-V peripherals - not suitable for sub-1.5-V cores. | Select when system requires ≥1.8-V rail and shares identical board space constraints. |
| TPS62841DLC | SON-8 package (1.5 mm × 2 mm); adds MODE and STOP pins; identical electrical specs. | Enables forced-PWM and noise-free measurement modes - requires larger PCB area and additional control signals. | Choose when design needs STOP-triggered quiet periods or dynamic PWM/PSM switching under firmware control. |
Compared with TPS62840YBG, TPS62841YBGR delivers lower output voltages essential for modern sub-1.2-V processors, while TPS62841DLC trades package size for functional flexibility - making TPS62841YBGR optimal for space-limited, fixed-voltage, always-on sensor nodes.

FAQ
What is the maximum output current supported by the TPS62841YBGR?
The TPS62841YBGR supports up to 750 mA of continuous output current across its full operating temperature range (–40°C to 125°C junction), verified under recommended conditions with 2.2-µH inductor and 10-µF output capacitor. Peak switch current limit is 1.2 A, ensuring reliable operation during transient loads without foldback.
Does the TPS62841YBGR include a STOP pin for noise-free measurements?
No, the TPS62841YBGR in WCSP-6 (YBG) package does not include a STOP pin - this feature is only available on SON-8 (DLC) and HVSSOP-8 (DGR) variants. The YBG version operates exclusively in Power-Save Mode with automatic PFM/PWM transition and no user-controllable switching halt function.
How is the output voltage set on the TPS62841YBGR?
The TPS62841YBGR uses a resistor (RSET) connected between VSET and GND to select one of 16 predefined output voltages from 0.8 V to 1.55 V in 50-mV increments. The internal R2D converter reads RSET during startup; E96-series values from 0.909 kΩ to 267 kΩ are supported, with ≤100 pF parasitic capacitance required at VSET.
What is the quiescent current of the TPS62841YBGR in 100% duty-cycle mode?
In 100% duty-cycle mode (VIN = VOUT), the TPS62841YBGR draws 120 nA typical quiescent current - measured at TJ = –40°C to 85°C with VOUT = 3.3 V. This ultra-low IQ extends usable battery life significantly when input voltage drops near the output level, such as in end-of-discharge scenarios.
Is the TPS62841YBGR RoHS-compliant and REACH-compliant?
Yes, the TPS62841YBGR is RoHS-compliant (lead-free, homogeneous material level) and meets REACH SVHC requirements per Texas Instruments' official product change notifications and material declarations. Full compliance documentation is available via TI's Quality & Environmental page for orderable part TPS62841YBGR.
