It drives two transistor outputs (positive configuration) at a fixed 200 kHz switching frequency, with a maximum duty cycle of 49%. The controller includes current limit and frequency control features, plus a synchronous rectifier drive output for efficiency. Packaged in an 8-pin PDIP (through-hole), it targets low-to-medium power offline and DC-DC converters where through-hole assembly or breadboard prototyping is preferred. ## Through-hole PDIP-8 — prototype-friendly, board-area tradeoff The 8-pin PDIP (0.300\" wide, 7.62 mm pitch) is a standard through-hole footprint. It sockets into a breadboard or a drilled PCB without reflow. ## Active lifecycle — no obsolescence pressure The UCC38084PG4 carries an Active product status from Texas Instruments. There is no last-time-buy notice or NRND flag. The ROHS3 compliance covers current environmental requirements.","metaTitle":"UCC38084PG4 PWM Controller, 200 kHz, 49% Duty Cycle, 8-PDIP","metaDescription":"UCC38084PG4 active PWM controller, 200 kHz switching, 49% max duty, buck/boost/half-bridge/push-pull, 4.1V-15V supply, 8-PDIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Bulk","Function":"Step-Up, Step-Down, Step-Up/Step-Down","Topology":"Buck, Boost, Half-Bridge, Push-Pull","Clock Sync":"No","Output Type":"Transistor Driver","Mounting Type":"Through Hole","Output Phases":"1","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Control Features":"Current Limit, Frequency Control","Duty Cycle (Max)":"49%","Number of Outputs":"2","Output Configuration":"Positive","Frequency - Switching":"200kHz","Operating Temperature":"0°C ~ 70°C (TA)","Synchronous Rectifier":"Yes","Supplier Device Package":"8-PDIP","Voltage - Supply (Vcc/Vdd)":"4.1V ~ 15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.06","stockQuantity":0,"priceTiers":[{"qty":146,"price":"$2.06000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c66dc9f92cbbdf419eefeda6ac058204.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the switching frequency of UCC38084PG4?","answer":"The switching frequency is fixed at 200 kHz.
