  • Description

    The APW7057 is a 300kHz constant frequency voltage mode synchronous switching controller that drives external N-channel MOSFETs. The upper MOSFET remains on when the input supply drops close to the output, achieving a 100% duty cycle. The internal loop compensation is optimized for fast transient response, eliminating the need for an external compensation network. This model features a precision 0.8V reference, making it suitable for a wide variety of low voltage applications. The soft-start time is internally set to 2ms, limiting the input in-rush current and preventing output overshoot during powering up.
