Description

Key Features

This user’s manual introduces not only performance of

a reference design with 45 W isolated flyback converter

using NCP11187 for auxiliary power supplies but also

provides key experimental results and information.

• Peak Current Mode Controller Integrated 800 V SJ−II

MOSFET, High Voltage Start−up, Soft−Start, and Slope

Compensation

• mWSaver

Best−in−Class Standby Power

Provides

Industry’s

NCP1118x is a highly enhanced switcher integrating

a peak current mode PWM controller employing

mWSavert and frequency reduction technology and

a highly robust 800 V Super−junction II MOSFET.

Additionally, it features a high−voltage startup circuit,

frequency reduction, slope compensation, constant output

power limit, and highly reliable and various protections. As

a results, it allows designing cost−effective off−line power

supplies using NCP1118x with less BOM counts and smaller

PCB size and high efficiency as well. Additionally, it could

get low standby power consumption less than typically

50 mW despite of multiple outputs.

On top of that, NCP1118x features variety of protections

for highly reliable power supply design such as a feedback

pin open−loop protection (OLP), current−sense resistor

short protection (CSSP), brown−out, line over−voltage

protection (Line−OVP) using an line voltage sensing pin

operated with auto−recovery operation and constant

over−power protection. This user’s manual demonstrates

those protections under various conditions.

• Switching Frequency Option: 65/100/130 kHz

• Proprietary Asynchronous Frequency Hopping

Technique for Low EMI

• Programmable Constant Output Power Limit for Entire

Input Voltage Range

• Precise Brown−out Protection and Line Over−voltage

Protection (LOVP) with Hysteresis

• Current Sense Short Protection (CSSP) and Abnormal

Over−Current Protection (AOCP)

• Thermal Shutdown (TSD) with Hysteresis

• All Protections Operated by Auto−recovery: VCC

Under−voltage Lockout (UVLO), Feedback Open−Loop

Protection (OLP), VCC Over−Voltage Protection (OVP)
