The ML4812CP from On Semiconductor is an integrated circuit designed for peak current control boost type power factor correction (PFC) systems. It incorporates a precision buffered 5V reference with ±0.5% accuracy, a current-input gain modulator for improved noise immunity, and a programmable ramp compensation circuit.
This device offers a 1A peak current totem-pole output drive and includes an overvoltage comparator to prevent output voltage runaway. Start-up is simplified by an under-voltage lockout circuit with 6V hysteresis. The ML4812CP operates within a voltage range of 12V to 18V and has an operating temperature range of 0°C to 70°C.
Designed for through-hole mounting, the ML4812CP is packaged in a 16-PDIP configuration. Its current consumption is rated at 800 µA. The IC functions as a current mode regulator, utilizing a product of sinusoidal line voltage and error amplifier output to control the cycle termination.
Key features include wide common mode range in current sense comparators for better noise immunity and a large oscillator amplitude. The control mode is Critical Conduction (CRM).
