About This Product

■Summary

MPQ2484U is a flexible multi-topology asynchronous controller for LED lights requiring high luminous intensity output. The device supports buck, boost, and buck-boost configurations, making it suitable for a wide range of LED lighting applications. The MPQ2484U has a wide input voltage (VIN) range of 4.5V to 45V and a maximum boosted output voltage of up to 75V. Peak current mode provides fast transient response and simplifies loop stabilization. The switching frequency (fSW) can be set via the FSET pin or synchronized to an external clock signal from 100kHz to 2.2MHz. A configurable frequency spread spectrum (FSS) feature allows you to periodically enable frequency dithering to improve EMI. The MPQ2484U provides switch-mode dimming by utilizing an external P-channel MOSFET. You can choose between two-step dimming or pulse-width modulation (PWM) dimming without a P-channel MOSFET. Robust fault protection includes thermal shutdown, cycle-by-cycle peak current limiting, output overvoltage protection (OVP), output short-circuit protection (SCP), LED open protection, and LED short-circuit protection. If a fault condition occurs, the fault indicator outputs an active logic low signal. The MPQ2484U is offered in a TSSOP-28EP package.
