IW1677 Overview
Key Specifications
Package: LSOP
Pins: 6
Length: 2.9 mm
Width: 1.6 mm
Description
The iW1677 is a high performance AC/DC power supply controller which uses digital control technology to build peak current mode PWM flyback power supplies. The device together with an external active device (depletion mode NFET or NPN BJT) provides a fast start-up without compromising no-load power loss.
Key Features
- while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost
- The iW1677 removes the need for secondary feedback circuitry while achieving excellent line and load regulation
- It also eliminates the need for loop compensation components while maintaining stability over all operating conditions
- Pulse-by-pulse waveform analysis allows for a loop response that is much faster than traditional solutions, resul
