GENERAL DESCRIPTION
The ADP5075 is a high performance dc-to-dc inverting
regulator used to generate negative supply rails.
The input voltage range of 2.85 V to 15 V supports a wide variety of applications. The integrated main switch enables the generation of an adjustable negative output voltage down to 39 V below the input voltage.
The ADP5075 operates at a pin selected 1.2 MHz/2.4 MHz switching frequency. The ADP5075 can synchronize with an external oscillator from 1.0 MHz to 2.6 MHz to ease noise filtering in sensitive applications. The
regulator implements programmable slew rate control circuitry for the MOSFET driver stage to reduce electromagnetic interference (EMI).
The ADP5075 includes a fixed internal o...
