2 Mhz Pwm Boost Switching Regulator

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 tran- sient response, ease of noise filtering, and also small, cost- saving external inductive and capacitive components. The current limit and the power Switch are integrated completely on chip. Capable of operating from 2.5 V to 5.5 V input, the ADP3031 is ideal for Thin-Film Transistor (TFT) Liquid Crystal Display (LCD) module applications, where local point-of-use power regulation is required. Featuring an adjustable output that supports voltages down to 3 V, the ADP3031 is ideal to generate todays low voltage rails, delivering power efficiently, and simply with minimal printed circuit board area. The device is specified over the industrial temperature range of -40C to +85C. By Analog Devices, Inc.
