| Parameter | ||
|---|---|---|
| Supply voltage | Same 10-30V-class controller envelope. | - |
| Memory & Peripherals | The class row is wide: LD7575 and NCP1251 walk the same mission with different feature emphases - the pin conventions agree more than the fine print does. | - |
| Case | SOP-8 / DIP-8 | SOT-23-6 / SOP-8 / DIP-8 / MSOP-8 |
| Compatibility Level | Functional Equivalent | - |
| Component Category | - | Offline Flyback PWM Controllers |
| Core & Architecture | A same-class current-mode flyback controller long listed beside the OB parts in repair cross-references: comparable power range and protection set, its own timing constants. | - |
| Firmware Notes | The cross-brand discipline for this whole class: power class, CS-pin protection scheme and (for certified products) the EMI spectrum are the three items to compare before treating two controllers as one. The circuits usually survive; the certification file may not. | - |
| Hardware Notes | Small-form packages per vendor; verify the pin drawing before layout-level swaps. | - |
| Lead Time Advantage | Shenzhen Spot Stock (24-48h Dispatch) | - |
| Market Reality | - | The OB2263 is the controller inside a sea of small chargers, adapters and set-top supplies: a current-mode flyback brain for the 1-30W class with the modern conveniences - frequency shuffling for EMI, burst mode for standby, full auto-recovery protection - that make a five-dollar adapter pass certification. Its role in repair is the one UB384x held in the previous generation: the small controller that dies when the surrounding components do, in circuits whose documentation is a reference design rather than a schematic. The class around it is wide and mostly interchangeable in concept - CR6842S, LD7575, NCP1251 and the OB siblings fly the same mission - and the substitution discipline is short: match the power class, check whether the frequency shuffling matters to the EMI file, and read the CS-pin protection scheme before swapping brands. |
