Visão Geral
Description
Key features include a high switching frequency (up to 2.1 MHz) for reduced component size, and low quiescent current for improved efficiency, particularly in light-load conditions. The device integrates a MOSFET switch, which contributes to its efficiency and simplifies the design process. It also includes protection features such as thermal shutdown, cycle-by-cycle current limit, and under-voltage lockout.
The LMR23610ADDAR is typically used in consumer electronics, automotive systems, industrial equipment, and any application requiring efficient voltage conversion in a small form factor. Its reliability and wide input voltage range make it versatile for various power management needs.
Equivalent
1. LM2596 by Texas Instruments – A 3-A step-down voltage regulator.
2. MP1584 by MPS – A 3-A synchronous step-down converter.
3. LMR33610 by Texas Instruments – Also a 36-V, 1-A converter.
4. LT8640 by Analog Devices – A 42-V, 5-A synchronous step-down regulator.
Ensure each alternative matches your specific application requirements such as input voltage range and efficiency.
Features
Key features include high efficiency, typically around 90%, due to its synchronous rectification topology. It supports a switching frequency of 2.1 MHz, allowing for the use of smaller external components, which helps reduce overall solution size. The converter also has a low quiescent current of 75 µA, which is beneficial for battery-powered applications.
Protection features include cycle-by-cycle current limit, thermal shutdown, and undervoltage lockout. It comes in a compact 8-pin SOIC package with PowerPAD for enhanced thermal performance. The LMR23610ADDAR is ideal for applications such as industrial systems, distributed power systems, and consumer electronics.
Pinout
Here are the pin functions for the LMR23610ADDAR:
1. SW (Pins 1-2): Switch node connected to the inductor.
2. VIN (Pin 3): Input voltage supply pin.
3. EN (Pin 4): Enable pin to turn the device on or off.
4. RT (Pin 5): Resistor timing pin to set the switching frequency.
5. FB (Pin 6): Feedback pin for output voltage regulation.
6. GND (Pin 7): Ground reference pin.
7. BOOT (Pin 8): Bootstrap capacitor connection for driving the high-side FET gate.
This configuration allows the LMR23610ADDAR to efficiently convert voltage for a wide range of applications, offering a balance between performance and size for compact designs.
