LM2735YQMF/NOPB

Voltage Regulators - DC DC Switching Regulators

AEC-Q100boost regulatorSEPIC520 kHzSOT-23-52.1 A switch limit

LM2735YQMF/NOPB is a 520 kHz AEC-Q100 Grade 1 boost and SEPIC controller for 2.7 V to 5.5 V input systems requiring regulated outputs up to 24 V.

Best for

  • Automotive 3.3 V or 5 V rail boost conversion
  • Low-voltage-input SEPIC conversion
  • Infotainment, cluster, ADAS, gateway, and TFT bias rails

Avoid if

  • Input voltage can exceed 5.5 V without an appropriate front-end arrangement
  • The required peak switch current exceeds 2.1 A minimum limit
  • A synchronous converter is required to reduce diode loss

Check before use

  • Use the Y version's 520 kHz switching frequency in magnetic-component calculations
  • Keep the SW-node loop short and route FB away from switching traces
  • Validate thermal margin across the -40°C to +125°C junction operating range
