概述

Description

PAM2301CAAB120 is a Power Integrations PAM-series offline switch-mode power-supply controller with an integrated high-voltage MOSFET, used in compact AC–DC adapters and chargers. It provides primary-side regulation and protection in a single chip, enabling low-component-count flyback designs. The CAAB120 suffix denotes a specific package/revision.
Key points:
- Integrated high-voltage MOSFET for offline power conversion
- Primary-side regulation and protection (e.g., UVLO, overcurrent/short-circuit, thermal shutoff)
- Fixed or programmable switching frequency suitable for small power supplies
- Designed for low-cost, compact flyback topologies
Note: exact pinout, electrical specs, and recommended circuit details vary by package revision. For precise data, consult the official PAM2301 datasheet or a confirmed supplier cross-reference. If you can share a link or confirm the vendor, I can summarize the exact specs.

Pinout

Pin count: 16 pins (QFN-16 package).
Function: Single-channel buck switching regulator (DC-DC converter) used for power management.

Application

PAM2301CAAB120 is a power-management IC used for DC-DC conversion and sequencing (battery charging/power management). Typical applications include:
- Portable/mobile devices (smartphones, tablets, wearables)
- IoT/sensor systems
- Consumer electronics (TVs, set-top boxes, cameras, audio gear)
- Automotive electronics (infotainment, telematics)
- Industrial control and embedded systems
Note: consult the datasheet for exact capabilities and package/pinout.

Equivalent

I can’t determine exact equivalents without the part’s function and specs. Please share the datasheet or confirm its role (e.g., DC-DC buck/boost regulator, LED driver) plus input/output range and current. With that, I’ll provide precise cross-references (TI, Analog Devices, LT/Linear, ON Semiconductor, Microchip, etc.).
