Overview
The COS384x series of controllers are peak current mode pulse width modulators. They are designed to offer improved performance and lowered external parts count when used in designing off-line or DC-to-DC switching power supplies. The internally implemented circuits include an under-voltage lockout (UVLO), featuring a start-up current of less than 1mA, and a precision reference trimmed for accuracy at the error amplifier input. Other internal circuits include logic to ensure latched operation, a pulse-width modulation (PWM) comparator that also provides current-limit control, and a totem-pole output stage that is designed to source or sink high-peak current. The output stage, suitable for driving N-channel MOSFETs, is low when it is in the off state.
Applications
- Solar Inverters
- Switching Regulators of Any Polarity
