Overview
The MP3362GJ-Z is a single-string boost LED driver IC from Monolithic Power Systems, designed for high-efficiency lighting applications. It operates with a minimum input voltage of 3V and supports output voltages up to 36V. The device features an adjustable switching frequency ranging from 200 kHz to 2.2 MHz and delivers an output current capability of 4A. Packaged in a TSOT23-8 surface-mount format, it supports both analog and PWM dimming methods. The component includes protection features such as open LED detection and thermal shutdown, ensuring reliable operation across a temperature range of -40°C to +125°C.
Feature Summary
- Supports both analog and pulse-width modulation (PWM) dimming techniques for precise light control
- Integrates open LED protection and thermal shutdown mechanisms for enhanced system safety
- Utilizes a low feedback voltage architecture to maximize conversion efficiency in boost topologies
Applications
- General solid-state lighting systems
- High-current boost LED driver circuits
- Low-current boost LED driver circuits
Procurement Notes
Verify the specific suffix 'Z' indicates RoHS compliance status according to manufacturer documentation. Confirm the package variant matches the required TSOT23-8 footprint for PCB layout compatibility. Ensure the selected operating frequency range aligns with external inductor specifications to maintain stable regulation under varying load conditions.
Selection Notes
Select this component when a single-channel boost topology is required for driving LED strings with inputs starting at 3V. Consider the 4A current limit for high-power applications or lower currents for efficiency optimization. Evaluate the need for combined analog and PWM dimming capabilities versus simpler control schemes before finalizing the design.
Part Context
This part belongs to the MP3362 series of fixed-frequency converters manufactured by Monolithic Power Systems. It is engineered specifically for boost applications where efficient power conversion is critical. The series distinguishes itself through its ability to handle both low and high-current scenarios within a compact surface-mount package.
Replacement Considerations
The MP3362GJ-P is a pin-compatible alternative within the same series, though it may differ in packaging quantity or specific trim characteristics. Verify functional equivalence regarding dimming support and protection features before substitution.
