This converter, which has an efficiency rating of 85%, guarantees optimal power use. It offers effective performance while retaining stability, switching at a frequency of up to 1000 kHz (Max). Fast mounting and secure transportation are both guaranteed by the tape and reel package. With a wide temperature range of -40 °C to 85 °C, this converter can endure the test in any environment. The TPS61041DBVR DC to DC converter will improve your power management abilities and open up new opportunities.
As a high-frequency boost converter designed specifically for small to big LCD bias supplies and white LED backlight sources, the TPS6104x shines. Whether using a dual-cell NiMH/NiCd battery or a single-cell Li-Ion battery, this adaptable device is ideal for generating output voltages up to 28 V. Additionally, it is excellent at converting 3.3 V or 5 V to 12 V using normal power conversions.
The TPS6104x allows for the use of small external components, such as ceramic and tantalum output capacitors, while operating at a phenomenal switching frequency of up to 1 MHz. Its attraction is further increased by the thin WSON package’s inclusion, which offers an incredibly small solution size. It is noteworthy that the TPS61040 variation has a 400-mA internal switch current restriction, while the TPS61041 variant has a 250-mA internal switch current limit. Due to this differentiation, output voltage ripple is reduced and smaller form factor inductors can be used to support lower power applications.
The TPS6104x offers outstanding operational efficiency over the whole load current range with a low quiescent current of just 28 A and an optimized control strategy. Utilize this cutting-edge boost converter’s superior power management abilities to guarantee top performance and efficiency in a variety of situations.
Key features of the TPS6104x boost converter include:
The TPS6104x boost converter has many useful features and a small size that make it a great choice for power control.
A high-frequency boost converter called the TPS6104x is designed for white LED backlight and small to medium LCD bias supply applications. This converter is great for making output voltages of up to 28 V from either a dual-cell NiMH or NiCd battery or a single-cell Li-Ion battery, thanks to its great features. The TPS6104x is designed to meet the specific needs of LCD bias supply and white LED backlight sets, so it can manage power and control voltage in a smooth way.
The TPS6104x is a boost converter that works well in a wide range of situations and is very efficient. With an input voltage range of 1.8 V to 6 V and an output voltage range of up to 28 V, this converter offers precise and flexible ways to handle power.
The TPS6104x uses a pulse-frequency-modulation (PFM) method with constant peak current control to make sure it is efficient over a wide range of load currents. With a switching frequency of up to 1 MHz, it lets you use small external parts, which saves room and makes the whole system easier to understand.
The converter reacts quickly to changes in the output voltage because it has smart feedback voltage monitoring. When the feedback voltage drops below the reference voltage of 1.233 V, an internal switch is released, which causes the current to ramp up. When the inductor current hits the peak current set by the switch, which is usually 400 mA (TPS61040) or 250 mA (TPS61041), the switch turns off.
To make sure the converter works safely and reliably, it is built with a typical maximum on-time of 6 s as a safety measure for extreme circumstances. During this process, the external Schottky diode is used to send the current to the output. It does this by being biased in the forward direction. The switch stays off for at least 400 ns, or until the feedback voltage again falls below the reference voltage.
The TPS6104x works in discontinuous conduction mode (DCM), where the switching frequency changes based on the output current and the PFM peak current control method. This dynamic regulation method allows for high efficiency over a wide range of load currents while keeping the built-in stability. This gives you more freedom to choose the right inductor and output capacitor.
The TPS6104x boost converter gives you better performance and stability, giving your ideas better power management and more precise voltage control.
The TPS6104x is a boost converter that is very flexible and efficient. It can be used in designs that need output voltages of up to 28 V. With an input voltage range of 1.8 V to 6 V and a switch peak current limit of 400 mA (or 250 mA for the TPS61041), this device can be used for a wide range of applications that require flexible voltage control.
The TPS6104x uses a pulse-frequency-modulation (PFM) method with constant peak current control to make sure that it works well and consistently no matter what the load current is. By using a switching frequency of up to 1 MHz, this converter makes it possible to use small external parts, which simplifies design and makes the best use of board space.
In conclusion, the Texas Instruments TPS61041DBVR DC to DC converter makes it easy to change voltage levels. It gives you exact control over the power in your circuit because it only has one output with a maximum current of 0.25 A. The wide range of voltage, from 1.8 V to 6 V, makes power control flexible and easy to change. The fact that its output voltage can be changed from 1.8 V to 28 V makes it even more useful.
It has a load regulation of 0.15%/mA (Typ) and a line regulation of 0.05%/V (Typ), which are both very good. With an efficiency rate of 85%, this converter makes the best use of power and wastes less energy. The tape and reel packaging makes installation and shipping easy and safe. It works perfectly in a wide range of temperatures, from -40 °C to 85 °C, and is made to handle tough conditions. Take charge of your power management needs and explore new areas with the TPS61041DBVR DC to DC converter, which combines efficiency and reliability.
