The ADP2300 and ADP2301 also support a wide input voltage range from 3 V to 20 V to accommodate a diversity of point-of-load applications, including consumer electronics and industrial and communications infrastructure equipment. This output voltage is adjustable from 0.8 V to 90 percent of input voltage (VIN). The regulator’s current-mode, fixed-frequency PWM (pulse-width modulation) architecture claims to provide excellent stability and transient response. Under light loads, the regulators automatically operate in PFM (pulse frequency modulation) to reduce light load losses.  A precision enable pin allows the regulator to be turned on at a precise input voltage for sequencing of multiple devices. System reliability and protection are enhanced further through OCP (overcurrent protection), UVLO (undervoltage lockout) and TSD (thermal shutdown).

Key features and benefits

• Frequency settings: ADP2300 (700 kHz) and ADP2301(1.4 MHz)
•  Input voltage supply range of 3 V to 20 V supports a diverse range of point-of-load applications
• Internal compensation and soft start provides easy design and PCB (printed circuit board) space saving
• Small TSOT packages provide a high-density solution and ideal replacement for less efficient linear regulators
• Automatic pulse frequency modulation improves efficiency under light loads
• Precision-enable pin allows the regulator to be turned on at a precise input voltage.

With a wide input voltage range up to 20 V, the ADP2300 and ADP2301 support a variety of signal-chain loads where circuits may include analog to digital converters, digital-to-analog converters, precision amplifiers and other high-performance, submicron ICs such as DSPs (digital signal processors) and FPGAs (field programmable gate arrays). The fast transient response and ease-of-use make these switching regulators a good match for powering FPGAs and Analog Devices’ Blackfin and SHARC processors.
