The ADP3031 is a high frequency, step-up DC-DC switching regulator capable of 12 V boosted output voltage in a space saving MSOP-8 package. It provides high efficiency, low-noise operation, and is easy to use. Capable of operating up to 2 MHz, the high switching frequency and PWM current mode architecture allow for excellent transient response, ease of noise filtering, and also small, costsaving external inductive and capacitive components. The current limit and the power switch are integrated completely on chip.
