What are the key features of LT8570IMS8E#TRPBF?
- 65 V internal switch rating supports boost conversion to high output voltages from input rails as low as 2.55 V, covering applications requiring 12 V to 48 V outputs from low-voltage batteries
- Configurable as boost, SEPIC, or inverting converter in a single 8-pin MSOP IC, reducing component count versus discrete multi-topology solutions
- Current-mode PWM control with integrated soft-start eliminates inrush current spikes during power-up, protecting sensitive loads in battery-powered and automotive systems
- Synchronization input allows the switching frequency to be locked to an external clock, reducing interference with sensitive analog or RF circuits sharing the same board
What is LT8570IMS8E#TRPBF used for?
The LT8570IMS8E#TRPBF is used in industrial and portable equipment power stages that require generating positive, negative, or regulated higher-voltage outputs from a single 2.55V to 40V input bus, such as 12V or 24V rails from a 3.7V Li-ion cell or 5V USB supply. Its SEPIC and inverting modes make it a single-IC solution for mixed-rail boards in wireless sensor nodes, handheld instruments, and industrial transmitters that need both positive and negative bias rails from a unipolar source. The 65V switch enables driving LED strings, OLED bias circuits, and industrial 4–20 mA transmitter rails that exceed the input supply voltage by several times.

Frequently Asked Questions
What converter topologies does LT8570IMS8E#TRPBF support and what switch voltage does it integrate?
The LT8570IMS8E#TRPBF supports boost, SEPIC, and inverting DC/DC converter topologies in a single IC. Its internal switch is rated for 65 V, allowing boost outputs well above the 2.55 V to 40 V input range, covering applications such as generating 48 V bus rails from a 12 V input or a negative 15 V rail from a 5 V supply.
How does the soft-start feature in LT8570IMS8E#TRPBF benefit battery-powered designs?
The integrated soft-start ramps the output voltage gradually at power-up rather than allowing an instantaneous step, limiting peak inrush current through the inductor and switch. In a 3.7 V Li-ion powered design boosting to 12 V at 200 mA, soft-start typically holds input inrush below 1 A during the startup ramp, preventing battery protection circuits from tripping and extending cell life by reducing high-current stress events.
When is LT8570IMS8E#TRPBF a better choice than a flyback controller for generating a negative supply?
For output currents below 300 mA at negative voltages down to negative 15 V, an inverting SEPIC built around LT8570IMS8E#TRPBF requires only one inductor, two capacitors, and a diode — far fewer components than a flyback that needs a coupled transformer wound to custom specifications. The LT8570 solution also avoids transformer parasitic ringing, simplifying EMI compliance on boards where PCB area and BOM cost are primary constraints.
What is the synchronization capability of LT8570IMS8E#TRPBF and why does it matter in RF or precision analog systems?
The sync input accepts an external clock signal that locks the converter's PWM switching frequency to a system reference. In a board combining LT8570IMS8E#TRPBF with a 433 MHz RF transceiver or a 16-bit ADC, synchronizing the switching frequency to a harmless sub-band — for example 1 MHz — prevents switching harmonics from aliasing into the ADC passband or desensitizing the RF front end, achieving better than 60 dB reduction in conducted switching noise at sensitive frequencies.
