Dual 600 mA buck regulator

Power Electronics / Power Management

3 February 2010 Power Electronics / Power Management

Analog Devices has introduced a miniature dual buck regulator for space-constrained portable electronic systems. At just 2 × 2 × 0,6 mm, the dual 600 mA ADP5022 includes an additional 150 mA on-chip LDO (low dropout regulator), a convenient feature for powering auxiliary rails.

In addition to being well suited for compact portable instruments and smart energy meters, the IC’s low-noise architecture and high switching frequency make it suitable for powering sensitive analog circuits like high-resolution ADCs (analog-to-digital converters).

The 3 MHz regulators included in the ADP5022 provide fixed-voltage outputs and internal compensation, delivering high efficiency and performance while minimising the external filter size and eliminating as many as 12 discrete components from system board design. To maintain high efficiency at both light and heavy loads, the device automatically shifts between PWM (pulse-width modulation) mode and PSM (power-save mode). The MODE pin can be used to force the device into PWM mode across all loads.

The ADP5022 provides important features that help enable the design of noise sensitive analog and RF systems. A key to designing sensitive analog circuits is getting the regulator physically close to the load. The compact size of the ADP5022 allows the system designer to place the power regulation right alongside the point of load, minimising PCB parasitics. The buck regulators employ a low-noise driver technique, high switching speed and out of phase clocking to further reduce noise.
