Overview
The LT1370CR#TRPBF is a high-efficiency switching regulator from Analog Devices, operating at a fixed 500 kHz frequency. It supports multiple topologies including Boost, Buck, Cuk, Flyback, Forward, and Inverting configurations. The device accepts an input voltage range of 2.7 V to 25 V and delivers up to 6 A output current with adjustable output voltage. Packaged in a DDPAK-7 surface-mount format, it features a shutdown function and operates within a commercial temperature range of 0°C to +70°C.
Feature Summary
- Supports versatile circuit topologies including boost, buck, cuk, flyback, forward, and inverting configurations for flexible power design.
Applications
- Portable equipment requiring efficient step-up or step-down conversion
- Battery-powered systems utilizing buck or boost architectures
- General-purpose DC-DC conversion in industrial control modules
Procurement Notes
Verify the specific suffix #TRPBF confirms tape-and-reel packaging versus tube variants like #PBF. Confirm the 'CR' grade matches the required commercial temperature range of 0°C to +70°C against datasheet specifications. Ensure compatibility with the DDPAK-7 footprint during procurement validation.
Selection Notes
Select this component when a single IC must support diverse converter topologies without external controller complexity. The 6 A capability suits moderate-to-high current loads, while the 500 kHz frequency balances component size and efficiency. Verify that the 2.7 V minimum input aligns with the source voltage profile.
Part Context
This part belongs to the LT1370 family of high-frequency current-mode switching regulators. It shares core architecture with other LT1370 variants but differs in package type and thermal rating. The CR designation indicates commercial grade operation, distinguishing it from extended temperature options.
