Analog Devices ADP244x's fast 50ns minimum on time enables the regulators to convert high-input voltage to low-output voltage at high frequency. The regulators use an emulated current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response. ADP244x's synchronization function enables the switching frequency to be synchronized with an external clock to minimize the system noise. Simple, reliable power sequencing is provided through the regulator's power-good output and precision-enable input.
The design of the ADP244x Switching Regulators provides a high-efficiency power solution with up to ±1 output accuracy in a 4mm x 4mm compact package.
