What are the key features of LT1534CS-1#PBF?
- Wide 2.7 V to 23 V input range with output adjustable from 1.3 V to 35 V, covering a broad set of boost and flyback converter topologies
- Current-mode PWM control architecture with slew-rate-limited switch transitions that reduce EMI by up to 20 dB compared to conventional regulators
- Internal 1.5 A switch rated for high peak currents, enabling efficient power delivery in compact transformer-based isolated supply designs
- Fixed 1.3 V internal reference with adjustable output set by two external resistors, simplifying design across multiple output voltage targets
What is LT1534CS-1#PBF used for?
The LT1534CS-1#PBF is optimized for telecommunications and industrial power supplies where low radiated EMI is a certification requirement, such as analog front-end bias rails and isolated DC-DC modules in medical and test equipment. Its wide input range and adjustable output also suit battery-powered portable devices that must step up from a 3.3 V or 5 V bus to higher voltages needed by LCD backlights, FPGA I/O banks, or high-voltage analog circuitry.

Frequently Asked Questions
How much does LT1534CS-1#PBF reduce EMI compared to a standard boost converter, and what enables that reduction?
The LT1534CS-1#PBF achieves up to 20 dB lower radiated EMI than conventional switchers by using slew-rate-limited gate drive on its internal 1.5 A switch. This controlled transition rate suppresses high-frequency spectral content, which is critical for designs needing to pass FCC Class B or CISPR 22 certification.
What is the input voltage range of LT1534CS-1#PBF, and can it operate directly from a single-cell Li-Ion battery?
The LT1534CS-1#PBF accepts input voltages from 2.7 V to 23 V. A single-cell Li-Ion battery discharges from approximately 4.2 V down to 2.7 V, so the converter can operate across the full battery discharge curve without dropout, making it a practical choice for handheld instruments requiring boosted rails.
What output voltage range can LT1534CS-1#PBF deliver, and how is the output voltage set?
The output is adjustable from 1.3 V to 35 V by selecting two external resistors that form a feedback divider against the 1.3 V internal reference. This flexibility allows the same LT1534CS-1#PBF to power circuits requiring 5 V, 12 V, or 24 V outputs without changing the IC, reducing design variants across a product family.
For a 16-pin SOIC layout, what are the key PCB placement guidelines to minimize noise on LT1534CS-1#PBF?
For the LT1534CS-1#PBF in a 16-pin SOIC footprint, keep the high-current switch node trace as short as possible, place input and output bypass capacitors within 5 mm of the supply pins, and route the feedback resistor divider away from the switch node. Ground plane copper poured under the IC helps dissipate heat and provides a low-impedance return path.
