About This Product

■Summary

The MPQ1542 is a 2A, 0.18Ω current mode step-up converter with an internal switch that provides a high efficiency regulator with fast response. The MPQ1542 can operate at 700kHz or 1.3MHz, allowing for easy filtering and low noise. An external compensation pin provides flexibility in setting loop dynamics, allowing the use of small, low-ESR ceramic output capacitors. Soft-start reduces inrush current and can be programmed with an external capacitor. The MPQ1542 operates with input voltages as low as 2.5V and can generate 12V at up to 500mA from a 5V supply. Protection features include undervoltage lockout (UVLO), current limiting, and thermal protection to prevent damage during output overloads. The MPQ1542 is available in a low profile, 8-pin MSOP package.

■Features and benefits

・2A, 0.18Ω, 25V power MOSFET ・Using small capacitors and inductors - Pin-selectable fixed switching frequency of 700kHz or 1.3MHz ・Programmable soft start - Operates with low input voltage of 2.5V and high output voltage of 22V ・12V at 500mA from 5V input ・Undervoltage lockout function (UVLO) and thermal shutdown ・Internal current limit ・Available in 8-pin MSOP package

■Available product numbers

・MPQ1542DK-LF-P MPQ1542DK-LF-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
