Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing applications, today introduced the ADP2300 and ADP2301 dc-to-dc switching regulators, the most recent in their growing portfolio of integrated power management switching regulators. The new 20V 1.2A (amp) step-down, dc-to-dc switching regulators integrate a high-side MOSFET that delivers power conversion efficiencies greater than 90 percent. The new regulators also feature internal loop compensation, integrated soft-start circuitry and bootstrap diodes to enable high-density solutions for intermediate bus generation and point-of-load regulation. The highly integrated ADP2300 and ADP2301 are available in small TSOT packages.
These 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 regulators’ current-mode, fixed-frequency PWM (pulse-width modulation) architecture provides 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
- 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 ADCs (analog to digital converters), DACs (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. Analog Devices’ integrated power management switching regulators are also supported by the ADIsimPower™ design tool, which makes selecting components, simulating power supply performance and building evaluation circuits easy and fast.
