What are the key features of LT8570IMS8E-1#PBF?
- Wide 2.55 V to 40 V input range covers battery, automotive, and industrial supply rails in a single converter solution
- Configurable as boost, SEPIC, or inverting topology provides design flexibility to generate positive or negative output voltages from a single IC
- 65 V maximum output voltage supports generating high-voltage rails for TFT LCD bias, industrial sensors, and piezo drivers
- Current-mode PWM control with 8-pin MSOP exposed-pad package enables compact, thermally efficient high-frequency switching designs
What is LT8570IMS8E-1#PBF used for?
The LT8570IMS8E-1#PBF is well suited for industrial sensor power supplies, portable test equipment, and automotive auxiliary rails where the input voltage varies widely and multiple output polarities or voltages are required from a single converter. Its SEPIC configuration handles input voltages that may be above or below the output without requiring a charge pump, making it ideal for single-cell lithium-ion battery designs. The inverting mode generates negative voltage rails for op-amp dual supplies, analog signal chains, and LCD bias circuits from a positive input source.

Frequently Asked Questions
What topologies can the LT8570IMS8E-1#PBF be configured in and which output voltages does each support?
The LT8570IMS8E-1#PBF can operate as a boost converter stepping up from its 2.55 V to 40 V input to outputs up to 65 V, as a SEPIC converter that regulates an output above or below the input from the same 2.55 V to 40 V range, or as an inverting converter generating negative output voltages such as -5 V or -12 V from a positive supply. This three-topology flexibility in a single 8-pin MSOP IC reduces design iterations across product variants.
How does the LT8570IMS8E-1#PBF's wide 2.55 V to 40 V input range benefit battery-powered and automotive designs?
The wide 2.55 V to 40 V input range lets the LT8570IMS8E-1#PBF operate directly from a discharged single-cell lithium-ion battery at 2.7 V on the low end and from a 24 V industrial bus or automotive 12 V to 36 V load-dump transient on the high end. This eliminates the need for pre-regulation or supply clamping, reducing BOM complexity in battery-operated instruments, 24 V industrial transmitters, and 12 V automotive accessories.
What is the switch current rating of LT8570IMS8E-1#PBF and how does this translate to output power capability?
The LT8570IMS8E-1#PBF has a switch current limit of 0.25 A. In a boost configuration from a 5 V input to a 12 V output with a typical 85% efficiency, this translates to approximately 100 mW to 150 mW of available output power, making it suitable for low-power auxiliary rails such as LCD bias voltages, op-amp supplies, and analog reference supply rails rather than high-current main power rails.
Which package does LT8570IMS8E-1#PBF use and how does the exposed pad affect thermal management?
The LT8570IMS8E-1#PBF uses an 8-pin MSOP package with an exposed thermal pad (MSOP EP). The exposed pad bonds directly to the PCB copper plane, reducing the junction-to-board thermal resistance to approximately 40°C/W to 50°C/W depending on PCB copper area. This is substantially better than a standard 8-pin MSOP without an exposed pad, allowing the IC to operate reliably at the full 0.25 A switch current without exceeding its maximum 125°C junction temperature in the industrial temperature range.
