What are the key features of LTC3769HFE#PBF?
- 60 V maximum input voltage with 4.5 V to 60 V operating range enabling boost conversion across a wide range of battery and supply conditions
- PassThru mode allows the output to directly connect to the input when the boost is not needed, reducing power dissipation during low-load conditions
- Voltage-mode PWM control with low quiescent current for efficient operation in battery-backed and always-on industrial systems
What is LTC3769HFE#PBF used for?
The LTC3769HFE#PBF is used in industrial and automotive power systems that require boosting from a variable battery source—such as a 12 V lead-acid or 24 V Li-ion pack—up to a regulated higher-voltage rail of 48 V or more. Its PassThru feature makes it especially effective in backup power applications and hold-up circuits, where the converter must seamlessly transition between boosting and pass-through modes as the input voltage fluctuates.

Frequently Asked Questions
What input voltage range does the LTC3769HFE#PBF support and what output voltages can it boost to?
The LTC3769HFE#PBF accepts input voltages from 4.5 V to 60 V, making it compatible with single-cell lithium-ion up to 48 V lead-acid battery systems. As a boost controller, it can regulate output voltages higher than the input, commonly targeting 12 V, 24 V, or 48 V rails depending on external component selection.
What is PassThru mode on the LTC3769HFE#PBF and when does a design benefit from it?
PassThru mode connects the input rail directly to the output through the boost switch network when the input voltage already meets the output regulation target, bypassing active switching. This eliminates switching losses during those operating conditions, improving overall efficiency by 2% to 5% in systems where the input frequently equals or exceeds the desired output, such as hold-up circuits with charged backup capacitors.
For a 20-pin TSSOP package, how does the LTC3769HFE#PBF compare to discrete boost controller implementations in terms of BOM complexity?
Integrating gate drive, voltage-mode PWM oscillator, soft-start, and fault protection into 20 pins reduces the external BOM to an inductor, output capacitors, power MOSFETs, and a handful of resistors and capacitors. A discrete implementation of the same functions might require 15 or more additional components across 100 mm² or more of PCB area.
