Primary-side feedback eliminates opto-isolators and simplifies design? Multi-mode operation for highest overall efficiency? Built-in cable drop compensation? Very tight output voltage regulation? No external loop compensation components required www. The device provides high efficiency along with a number of key built-in protection features while minimizing the external component count and bill of material cost.

The iW 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, resulting in improved dynamic load response.

The built-in power limit function enables optimized transformer design in universal off-line applications and allows for a wide input voltage range. The low start-up power and PFM operation at light load ensure that the iW is ideal for applications targeting the newest regulatory standards for standby power.

Built-in output constant-current control with primary-side feedback? Low start-up current 10?? A typical? Built-in soft start? Built-in short circuit protection? PFM operation at light load? Space-saving SOT package 3. Ground connection. Supply voltage. Primary current sense. Used for cycle-by-cycle peak current control and limit.

This further reduces both the BOM size and cost and allows ultra-compact power adapters as small as 2cm x 2cm x 1. Because it is controlled via a configuration pin option, the CDC option simplifies product options, ordering and inventory challenges. This unique technology uses proprietary digital algorithms to eliminate the need for a secondary iawtt regulator and optical feedback isolator, lowering the total BOM cost, reducing the overall solution size, and improving reliability.
