DC DC Switching Controllers datasheet and documents for UCC3895DWTR
DC DC Switching Controllers Overview
The UCC3895DWTR is a BiCMOS advanced phase-shift PWM controller designed for full-bridge power stages. It supports switching frequencies up to 1 MHz and operates within a supply voltage range of 9 V to 16.5 V. The device provides four outputs with a maximum duty cycle of 100% and an output current capability of 100 mA. It functions in SOIC-20 packages, supporting surface-mount installation. The operational temperature range spans from 0°C to +70°C.
DC DC Switching Controllers Feature Summary
- Enables zero-voltage switching through phase-shifted control logic for high-frequency efficiency
- Supports voltage mode, peak current mode, or average current mode regulation
- Features programmable soft-start, soft-stop, and shutdown via a single pin
- Includes adaptive delay settings and bidirectional oscillator synchronization
DC DC Switching Controllers Applications
- Communication and network power supplies
- Signal processing power management systems
- High-efficiency DC/DC converters requiring resonant switching
DC DC Switching Controllers Procurement Notes
Verify the specific suffix 'DWTR' corresponds to the SOIC-20 package and tape-and-reel configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet revision to confirm feature availability.
DC DC Switching Controllers Selection Notes
Select this component when designing full-bridge topologies requiring phase-shift control. It is suitable for applications needing combined constant frequency PWM and resonant ZVS operation. Consider the 1 MHz maximum frequency limit and 100 mA output drive capability. Evaluate the BiCMOS工艺 benefits regarding lower quiescent current compared to bipolar alternatives.
DC DC Switching Controllers Part Context
This part belongs to the UCC3895 series, which enhances the UC3875/6/7/8 family. It utilizes BCDMOS technology to reduce operating supply current. The device integrates enhanced control logic and adaptive delay features not present in earlier generations. It serves as a direct functional upgrade for legacy designs requiring higher efficiency at increased switching frequencies.
DC DC Switching Controllers Replacement Considerations
Public confirmed substitutes include UCC3895DW and UCC3895PWTRG4. Verify package compatibility (SOIC-20 vs TSSOP-20) and temperature grade differences before substitution.
