DC DC Switching Controllers datasheet and documents for LTC1929CG-PG#TRPBF
DC DC Switching Controllers Overview
The LTC1929CG-PG#TRPBF is a dual-phase synchronous buck switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 36V and supports a fixed switching frequency between 150kHz and 300kHz. The device utilizes current-mode control to ensure phase synchronization and load sharing, delivering up to 3A per phase. It features OPTI-LOOP compensation for improved transient response and includes a power good output monitor.
DC DC Switching Controllers Feature Summary
- Dual-phase architecture reduces input capacitance requirements and minimizes power supply induced noise.
- Current-mode control ensures precise current sharing between phases.
- OPTI-LOOP compensation improves transient response performance.
- Integrated power good output voltage monitor.
DC DC Switching Controllers Applications
- High-efficiency synchronous step-down conversion
- Automotive power management systems
- Industrial point-of-load regulation
DC DC Switching Controllers Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when placing orders. Confirm that the PG variant includes the integrated power good monitor feature as specified in official documentation. Ensure compatibility with the required operating temperature range and package type before procurement.
DC DC Switching Controllers Selection Notes
Select this component for applications requiring reduced input ripple and noise through dual-phase operation. The wide input voltage range suits various bus architectures. Current-mode control is ideal for demanding transient loads. Verify that the fixed frequency range aligns with system EMI constraints.
