iW1600 Product Summary Off-Line Digital Green-Mode Quasi-Resonant PWM Controller 1.0 Features 2.0 Description ●● Ultra-low no-load power consumption with lowest system costs (< 10mW at 230VAC in typical 5V/2A power supplies) The iW1600 is a high performance AC/DC power supply controller that uses digital control technology to build peak current mode PWM flyback power supplies. The device directly drives a power BJT and operates in quasiresonant mode to provide high efficiency along with a number of key built-in protection features while minimizing the external component count, simplifying EMI design, and lowering the total bill of material cost. The iW1600 removes the need for secondary feedback circuit 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 optimizes transformer design in universal off-line applications and allows for a wide input voltage range. ●● Fast dynamic response with secondary-side load transient detection without opto-coupler ●● Built-in fast startup ●● Direct drive of low-cost BJT power switch achieving high efficiency ●● Tight constant-voltage and constant-current regulation across line and load range with primary-side feedback and control ●● Intelligent low power management achieves ultra-low operating current at no-load ●● Proprietary optimized line/load adaptive maximum constant frequency PWM switching with quasi-resonant operation achieves best size, efficiency, and common mode noise ●● User-configurable 4-level cable drop compensation provides design flexibility ●● EZ-EMI® design enhances manufacturability ●● Adaptive multi-mode PWM/PFM control improves efficiency ●● No external loop compensation components required ●● Built-in single-point fault protections against output short-circuit, output over-voltage, and output overcurrent Dialog’s innovative proprietary technology ensures that power supplies built with the iW1600 and the secondary -side voltage positioning controller iW600 can achieve both the highest average active efficiency and less than 10mW no-load power consumption, and have fast dynamic load response in a compact form factor in typical 5V2A 10W applications. The active start-up scheme enables the shortest possible start-up time without sacrificing no-load power loss. 3.0 Applications ●● On-chip internal over-temperature protection ●● Compact AC/DC adapters or chargers for media tablets and smart phone ●● No audible noise over entire operating range ●● AC/DC adapters for consumer electronics ●● SmartDefender™ smart hiccup technology helps address issues of soft shorts in cables and connectors by effectively reducing the average output power at fault conditions without latch iW1600 Product Summary Rev. 0.93 Preliminary 1 of 5 © 2015 Dialog Semiconductor (UK) Ltd. iW1600 Product Summary Off-Line Digital Green-Mode Quasi-Resonant PWM Controller L 2 iW600 1 D1 + VOUT + N RTN U1 iW1600 1 VSENSE 2 GND VCC 8 + GND 7 OUTPUT 6 4 HV CS/CDC 5 RCDC Figure 3.1: iW1600 Typical Application Circuit (Achieving < 10mW No-load Power Consumption in 5V2A 10W Adapter Designs with iW600 Secondary Voltage Position IC) 4.0 Pinout Description iW1600 1 VSENSE VCC 8 2 GND GND 7 OUTPUT 6 CS/CDC 5 4 HV Figure 4.1: 7 Lead SOIC-7 Package Pin # Name 1 VSENSE 2 GND 4 HV 5 CS/CDC 6 OUTPUT Output Base drive for BJT. 7 GND Ground Ground. 8 VCC iW1600 Product Summary Type Pin Description Analog Input Auxiliary voltage sense.
