Overview
The LT3758AMPMSE#PBF is a high input voltage switching regulator controller from Analog Devices, designed for boost, flyback, SEPIC, and inverting topologies. It operates with an input voltage range of 5.5 V to 100 V and supports a switching frequency between 100 kHz and 1 MHz. The device features a low static current of 100 nA and a maximum operating junction temperature of +150°C. It provides one output channel capable of positive, negative, or isolated outputs, housed in a 10-MSOP-EP package.
Feature Summary
- Supports multiple converter topologies including boost, flyback, SEPIC, and inverting configurations
- Enables clock synchronization for multi-phase or parallel operation
- Integrates soft-start functionality to manage inrush currents during startup
- Features enable pin control for power management and system shutdown
Applications
- Industrial power supply systems requiring high input voltage tolerance
- Battery-powered equipment utilizing boost or SEPIC architectures
- Automotive electronics demanding extended temperature range operation
- Telecommunications infrastructure power modules
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and RoHS standards before procurement. Confirm the package variant matches the required MSOP-10 footprint with exposed pad. Ensure the A-grade temperature rating aligns with the application's thermal requirements. Cross-reference the datasheet revision to confirm feature consistency. Validate supplier authenticity through authorized distribution channels.
Selection Notes
Select this component when designing circuits requiring high input voltage handling up to 100 V without external level shifting. Consider the 100 nA quiescent current for battery-sensitive applications. Choose the MSOP-10 package for space-constrained designs requiring thermal dissipation via the exposed pad. Evaluate the 150°C junction temperature limit for harsh environment deployments.
Part Context
This part belongs to the LT3758 family of high voltage DC-DC controllers. It complements other Analog Devices power management solutions by offering flexible topology support. The AM grade denotes an extended industrial temperature range compared to standard commercial grades. It serves as a core control element for various off-line and isolated power conversion stages.
Replacement Considerations
LT3758EMSE#PBF offers similar functionality but may differ in temperature grade specifications. LT3758AMPMSE#TRPBF provides identical electrical characteristics but utilizes tape-and-reel packaging instead of tubes. Verify pinout compatibility and thermal performance metrics when substituting.
