What are the key features of TPS61041DRVRG4?
- Adjustable output voltage from 1.8 V up to 28 V from a 1.8 V to 6 V input enables white LED backlighting and OLED bias generation from a single-cell Li-ion battery
- Pulse frequency modulation current-mode control achieves high efficiency across a wide 0.05 A to micro-ampere load range, minimizing quiescent current in battery-powered designs
- Ultra-compact 6-pin WSON package with exposed thermal pad allows PCB footprints under 2 mm × 2 mm, ideal for space-constrained wearables and handheld displays
- Fixed current limit and automatic soft-start prevent input inrush and output overshoot during startup, protecting sensitive OLED and LED loads
What is TPS61041DRVRG4 used for?
The TPS61041DRVRG4 is the industry-standard solution for boosting a single-cell Li-ion battery (2.7 V to 4.2 V) to the 16 V to 22 V bias rail required by passive-matrix OLED displays and white LED string backlights in portable medical devices, e-paper modules, and wearable fitness trackers. Its 28 V maximum output and PFM control maintain high efficiency even when display brightness is reduced to microampere standby currents, extending battery life significantly versus fixed-frequency converters. The miniature WSON package enables placement close to the display connector, minimizing EMI and voltage drops on the boost output trace.

Frequently Asked Questions
What input and output voltage ranges does the TPS61041DRVRG4 support for OLED display bias generation?
The TPS61041DRVRG4 accepts input voltages from 1.8 V to 6 V and boosts to an adjustable output from 1.8 V up to 28 V using an external resistor divider. This range directly covers the 16 V to 22 V bias voltages required by most passive-matrix OLED panels when powered from a 3.3 V or 3.7 V single-cell Li-ion battery.
How does PFM control in TPS61041DRVRG4 improve battery life versus fixed-frequency PWM boost converters?
Pulse frequency modulation skips switching cycles when the output capacitor holds sufficient charge, reducing average quiescent current at light loads to microampere levels. In contrast, a fixed-frequency PWM converter switches every cycle regardless of load, consuming 50 µA to 200 µA quiescent. In a wearable device drawing 1 mA average, the PFM topology can extend battery life by 10% to 20% compared to a PWM converter of similar output capability.
What maximum output current can the TPS61041DRVRG4 deliver, and is it sufficient for white LED backlighting?
The TPS61041DRVRG4 delivers up to 50 mA output current at its maximum 28 V output. For a 4-LED string at 20 mA per LED in parallel configuration, or a 2-LED series string at 20 mA, the 50 mA capability is sufficient for a typical handheld display backlight. For higher brightness requiring 100 mA or more, a higher-current boost converter such as the TPS61040 or TPS61085 would be more appropriate.
How does the 6-pin WSON package of TPS61041DRVRG4 compare in area to an SOT-23 boost converter package?
The 6-pin WSON (also called SON or DRV) package measures approximately 1.5 mm × 1.5 mm with a 0.5 mm pitch, giving a land area under 2.25 mm². An SOT-23-5 package measures roughly 2.9 mm × 1.6 mm, or about 4.6 mm² land area. The WSON is therefore approximately 50% smaller, directly benefiting ultra-compact wearable and hearing aid PCB designs where board space is at a premium.
