| Not Recommended for New Design 2 Channel Linear Controller with Independent Enable Function AP451 - Features - 2 channel linear control Circuitries - Operating voltage can be up to 18V - Under Voltage Lockout UVLO Protection - Current limit external BJT only - Independent enables function - Low ESR output capacitor Multi-layer chip capacitor MLCC application - Adjustable output voltage by external resisters - 0.8V voltage reference Output - NPN or N-channel MOSFET driving capability - 8-pin SOP, PDIP Pb-Free packages - Applications - LCD Monitor/TV - XDROM, XDSL Product - M/B, VGA - Pin Assignment Top View OUT1 1 FB1 2 EN1 3 GND 4 AP451 8 Vcc 7 OUT2 6 FB2 5 EN2 SOP-8L/PDIP-8L - General Description The AP451 integrates two channel linear controllers into a single chip, mainly designs for power-supply regulator. All the functions included an on-chip 0.8V reference output, an error amplifier, UVLO, current limit. During low VCC situation, the UVLO makes sure that the outputs are off until the internal circuit is operational normally. - Pin Descriptions Pin Name No. OUT1 1 Linear Controller CH1output FB1 2 Channel 1 Voltage Feedback EN1 3 Channel 1 Enable Pin GND 4 Signal Ground EN2 5 Channel 2 Enable Pin FB2 6 Channel 2 Voltage Feedback OUT2 7 Linear Controller CH2 output Vcc 8 Supply Voltage - Ordering Information AP451 X Package S SOP-8L N PDIP-8L Packing Blank Tube A Taping This datasheet contains new product information.
