MPQ2484 - Multi-Topology LED Controller

General Description

The MPQ2484 is a flexible, multi-topology, asynchronous controller for LED lights with a high brightness.

The device supports buck, boost, and buck-boost configurations, which makes it well-suited for multi-purpose applications.

Key Features

  • a wide 4.5V to 45V input voltage (VIN) range, with a maximum boost voltage up to 75V. Peak current mode operation provides fast transient response and eases loop stabilization. The switching frequency (fSW) can be set by the FSET pin, or it can be synchronized by a 100kHz to 2.2MHz external clock signal. The configurable frequency spread spectrum (FSS) function can periodically enable dither switching to improve EMI. The MPQ2484 provides dimming switch mode with a P-channel MOSFET. During normal.
