MPQ3432 Synchronous Boost Converters
Monolithic Power Systems (MPS) MPQ3432 Synchronous Boost Converters support up to 20W of load power from a single-cell battery with integrated low RDS(ON) power MOSFETs. These converters start-up from an input voltage (VIN) as low as 2.7V and adopt Constant-Off-Time (COT) control to provide a fast transient response. The MPQ3432 boost converters feature configurable switch peak current limit, 600kHz fixed switching frequency (fSW), and external soft start and compensation pins. The configurable current limit provides accurate overload protection. The MODE pin allows the user to select Pulse-Skip Mode (PSM), Forced Continuous Conduction Mode (FCCM), or Ultrasonic Mode (USM) under light-load conditions. These boost converters offer various protection features, including configurable input Under-Voltage Lockout (UVLO) and Over-Temperature Protection (OTP). The MPQ3432 boost converters operate within the -40°C to 125°C temperature range and are available in a QFN-13 (3mm x 4mm) package. Typical applications include automotive boost, supercapacitors, and backup batteries.
