概述
Description
MIC2290YML-TR is a Micrel/Microchip MIC2290 family high-efficiency buck regulator in a small YML package, delivered in tape-and-reel (-TR). It’s a DC-DC step-down converter with an integrated high-side switch and control circuitry, designed to convert a higher input voltage to a stable lower output for portable and battery-powered applications.
Key points:
- Type: fixed-frequency, current-mode buck regulator with protection (e.g., current limit, thermal shutdown) and soft-start.
- Packaging: YML is a compact lead-frame package; -TR indicates tape-and-reel for automated assembly.
- Interface: typically adjustable output via a feedback network (or fixed variants), plus enable/shutdown control.
- External components: inductor, input/output capacitors, and feedback resistors.
- Applications: power supplies for microprocessors, telecom, LCD biasing, and other low-to-moderate voltage DC-DC needs.
For precise electrical specs (input range, output voltage options, switching frequency, efficiency, pinout), consult the MIC2290 datasheet and product page.
