Visão Geral
Description
The converter also features internal synchronous rectification, which enhances efficiency by reducing power loss. Additional features include a low dropout operation, internal soft start, and power good indicators. It is packaged in a compact 4mm x 4mm QFN package, making it ideal for space-constrained applications. This component is commonly used in portable electronics, distributed power systems, and other applications requiring high efficiency and compact design.
Equivalent
1. Texas Instruments TPS54286 - Dual Synchronous Buck Converter.
2. On Semiconductor NCP81253 - Dual Buck Controller.
3. Microchip Technology MCP16331 - Step-Down Regulator (though not dual, it's similar in function).
Specific requirements like input voltage, output current, and package type should be considered when selecting an equivalent.
Features
Key features include:
- Dual Output: It provides two independent outputs, capable of delivering up to 1A each.
- High Efficiency: Operates with efficiencies up to 95% to prolong battery life.
- Frequency Synchronization: Offers a selectable switching frequency from 1.5MHz to 4MHz, allowing trade-offs between efficiency and component size.
- Low Noise: Features a low output ripple, making it suitable for noise-sensitive applications.
- Current Mode Operation: Ensures fast transient response and easy loop compensation.
- Compact Design: Available in a compact 4mm x 4mm QFN package, supporting space-constrained designs.
- Power-Saving: Includes Burst Mode operation to improve efficiency at light loads.
- Protection: Comes with over-temperature and short-circuit protection.
These features make the LTC3417AEDHC well-suited for a variety of portable devices and applications requiring efficient power management.
Pinout
Key pin functions include:
- VIN1 and VIN2 (Pins 1 and 2): Input voltage supply for the two converters.
- SW1 and SW2 (Pins 3 and 4): Output switching nodes for each converter.
- FB1 and FB2 (Pins 5 and 6): Feedback inputs for setting the output voltage.
- RUN1 and RUN2 (Pins 7 and 8): Enable pins for the converters.
- PGOOD1 and PGOOD2 (Pins 9 and 10): Power good indicators.
- GND (Pin 11): Ground connection.
Additional pins are for compensation, soft-start, and mode selection. This device is used in applications requiring efficient voltage conversion and regulation, such as portable electronics.
