Product details

Boost regulator for high-voltage bias rails

It accepts an input from 1.8 V up to 6 V and can produce an output as high as 28 V, making it a fit for biasing OLED displays, driving avalanche photodiode (APD) bias, or powering MEMS micro-mirror drivers where a moderate current at elevated voltage is needed.

Switch current and output capability

At a 28 V output, the maximum practical load current is limited by the switch duty cycle and inductor losses.

Switching frequency and external component sizing

The switching frequency operates up to 1 MHz. This allows the use of small-value inductors and ceramic output capacitors, keeping the total solution footprint compact.

Frequently asked questions

What is the current stock status of TPS61045ADRBT?

Buyers need instant availability to avoid project delays; out-of-stock forces alternative sourcing.

What is the datasheet for TPS61045ADRBT?

Designers require full specifications to verify fit in the circuit before purchase.

Is TPS61045ADRBT active or obsolete?

Lifecycle status determines long-term design viability and risk of supply discontinuation.

What is the lead time for TPS61045ADRBT?

Production planners need accurate lead times to schedule manufacturing without interruptions.

What are the equivalent or replacement options for TPS61045ADRBT?

If the part is unavailable, an exact cross-reference or substitute keeps the BOM viable.

What is the price of TPS61045ADRBT per quantity?

Cost comparison drives sourcing decisions; volume pricing affects project budget.
