MPQ3426

MPQ3426 6A, 45V, Boost Converter with Configurable Switching Frequency and UVLO AEC-Q100 Qualified DESCRIPTION The MPQ3426 is a current-mode step-up converter with a 6A, 90mΩ, 45V internal switch that provides a highly efficient regulator with a fast response. The MPQ3426 features a configurable switching frequency (fSW) of up to 2MHz that allows for simple filtering and reduces noise. An external compensation pin gives the user flexibility in setting loop dynamics, and allows the user to use small, low-ESR, ceramic output capacitors. Soft start leads to a small inrush current that can be configured with an external capacitor. The MPQ3426 operates from a biased supply voltage as low as 3.2V, and can generate an output voltage (VOUT) up to 35V. The MPQ3426’s features include under-voltage lockout (UVLO), current limiting, and thermal overload protection. The MPQ3426 is available in a low-profile QFN14 (3mmx4mm) package and a QFN-14 (4mmx4mm) package with wettable flanks and an exposed pad. FEATURES 6A, 90mΩ, 45V Power MOSFET Supports Battery Range up to 45V (Load Dump) Wide Input Voltage (VIN) Biased Supply Range: 3.2V to 22V Ideal for Automotive Pre-Boost Applications Output Voltage (VOUT) as High as 35V Configurable 300kHz to 2MHz Switching Frequency (fSW) Micro-Power Shutdown <1μA Thermal Shutdown at 160°C Available in a QFN-14 (3mmx4mm) Package Available in a QFN-14 (4mmx4mm) Package with Wettable Flanks Available in AEC-Q100 Grade 1 APPLICATIONS Au...
