These solutions are targeted at AC-DC adapter applications for laptop/notebook computers, LCD displays, printers, and household consumer electronics.

ON Semiconductor (Fort Worth, TX) (Nasdaq: ONNN) has expanded its portfolio of AC-DC power solutions for home electronics with the introduction of  the NCP1234 and NCP1236 family of fixed frequency pulse width modulation (PWM) current mode controllers. These solutions are targeted at AC-DC adapter applications for laptop/notebook computers, LCD displays, printers, and household consumer electronics. Features include:

• A high voltage process technology.
• Over power compensation, brownout (NCP1236 only), and ramp compensation.
• High voltage Dynamic Self-Supply (DSS) technology, which enables direct connection to the line voltage eliminating the need for startup resistors.
• Available in 2 frequency options, 65 or 100 kHz with the option to automatically recover, or latch off the device during a fault condition. 
• Housed in an SOIC-7 package.
