Overview
The LT1172CQ#PBF is a monolithic high-power switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 60 V and provides an adjustable output voltage with a maximum output current of 1.25 A. The device supports multiple topologies including buck, boost, flyback, forward, inverting, and Cuk configurations. Key electrical parameters include a fixed switching frequency of 100 kHz and a quiescent current of 6 mA. It functions within a temperature range of 0°C to +100°C and is housed in a DDPAK-5 surface-mount package.
Feature Summary
- Integrates a high-current, high-efficiency power switch with complete oscillator, control, and protection circuitry on a single die.
- Capable of operation in all standard DC-to-DC switching configurations, providing design flexibility for various power conversion needs.
- Designed for high efficiency performance across a wide input voltage range without requiring external shutdown functionality.
Applications
- Positive Buck Converter applications
- Forward Converter implementations
- Flyback Converter designs
- Negative Boost Regulator circuits
Procurement Notes
Verify component availability status prior to procurement planning, as the manufacturer indicates restricted supply conditions for this specific part number. Confirm that the DDPAK-5 package and RoHS compliance meet your assembly requirements. Ensure that the operating temperature range of 0°C to +100°C aligns with your system's thermal environment specifications before finalizing orders.
Selection Notes
Select this component when a versatile, high-power switching regulator is required for multiple topology implementations. The integrated high-current switch simplifies design by reducing external component count. Consider the 100 kHz switching frequency and 1.25 A output capability against your specific power density and efficiency targets. Verify that the adjustable output voltage feature meets your precise regulation requirements.
Part Context
This part belongs to the LT1172 series of high-efficiency switching regulators from Analog Devices. The series is characterized by its ability to function in various standard converter topologies using a single monolithic IC. The LT1172CQ#PBF specifically denotes the commercial grade version in a tube packaging format, distinguishing it from other suffix variants that may offer different temperature ranges or package styles.
Replacement Considerations
Consult official Analog Devices documentation for verified substitute part numbers within the LT1172 family. Ensure any replacement maintains compatibility with the DDPAK-5 footprint and matches the 3 V to 60 V input voltage specification. Verify that alternative components support the same 100 kHz switching frequency and 1.25 A output current capabilities.
