... Soft start User initiated micropower “Sleep Mode” Description The PFC IR1150 is a power factor correction (PFC) control IC designed to operate in continuous conduction mode (CCM) over a wide range input line voltages. The IR1150 is based on IR's proprietary "One Cycle Control" (OCC) technique providing a cost effective solution for PFC ...

... General Description The PFC IR1150 is intended for boost converters for power factor correction operating at a fixed frequency in continuous conduction mode. The IC operates with two loops; an inner current loop and an outer voltage loop. The inner current loop is fast, reliable and does not require sensing of the input voltage in order to create a current reference ...

... To prevent noise problems, a bypass ceramic capacitor connected to V and COM should be CC placed as close as possible to the IR1150. This pin is not internally clamped, therefore damage will occur if the maximum voltage is exceeded. OVP/EN: Over Voltage Protection / Enable This pin is the input to the over voltage protection comparator the threshold of which is internally pro- grammed to 105 ...
