LT1247CS8#PBF

Overview

The LT1247CS8#PBF is a switching controller from Analog Devices Inc., designed for buck topology applications. It operates as a 1MHz off-line current mode PWM and DC/DC converter. The device features a single output capable of delivering up to 1A at 5V. It functions within a supply voltage range of 7.6V to 25V, consuming 13mA of operating current. The component supports a maximum duty cycle of 100% and is rated for operation between 0°C and +100°C. It is housed in an 8-pin SOIC package.

Feature Summary

Implements current mode PWM control for efficient power conversion
Supports non-isolated buck topology with high-frequency switching
Enables continuous conduction via 100% maximum duty cycle capability

Applications

Off-line power supply designs
General-purpose DC/DC step-down conversion
Industrial equipment power management

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm that the SOIC-8 package matches your PCB footprint requirements. Ensure the input voltage range of 7.6V to 25V aligns with your system design before procurement. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components.

Selection Notes

Select this controller for applications requiring a compact buck regulator solution with fixed frequency operation. Consider the 1MHz switching frequency for smaller passive component sizes compared to lower-frequency alternatives. Evaluate the thermal performance within the specified temperature range. Verify that the single-output configuration meets the load requirements without needing additional channels.

Part Context

This component belongs to the LT1247 series of switching controllers manufactured by Analog Devices Inc. It is categorized under PMIC - Power Management ICs. The device serves as a core control element for offline and DC/DC converters, providing stable regulation through current mode PWM techniques in a small surface-mount package.
