ADP5014 Integrated Power Solution

Analog Devices Inc. ADP5014 Integrated Power Solution incorporates four high-performance, low-noise buck regulators. Due to its low output noise (~25μ Vrms when V_OUT ≤ V_REF), the buck regulators enable the powering up of the noise-sensitive signal chain products. Each channel of the ADP5014 includes high-side and low-side power MOSFETs. Channel 1 and Channel 2 provide a programmable output current of 2A or 4A. ADP5014's Channel 3 and Channel 4 have a programmable output current of 1A or 2A. Combining Channel 1 and Channel 2 or Channel 3 and Channel 4 in parallel configuration can deliver a single output with up to 8A or 4A respectively. Designers can program or synchronize the ADP5014's switching frequency from 500kHz to 2.5MHz using an external clock. The ADP5014 from Analog Devices offers two enable modes. The manual mode has four individual precision enable pins to enable each regulator manually. Alternatively, the sequence mode has one grouped precision enable signal with programmable power-up and power-down delay timers on each rail for specific rail sequence requirements.
