The ADP2311 is a fully integrated, dual output, synchronous step-down dc-to-dc regulator. The regulator operates from input voltages of 4.5 V to 18 V, and the output can regulate down to 0.6 V. Each channel can provide up to 1 A of continuous output current.
The ADP2311 integrates the high-side and low-side MOSFETs to provide a very high efficiency, compact solution. Both channels of the regulator run at 180° out of phase to reduce the input ripple current and the input capacitor size, thereby helping to lower system electromagnetic interference (EMI). The ADP2311 also integrates internal compensation and soft start circuitry to simplify the design.
An on-chip watchdog timer can reset the microprocessor if it fails to strobe within a preset timeout period. Accurate voltage monitoring circuitry and a power fail comparator provide a controlled power-up and power-down sequence to enhance system reliability.
The ADP2311 also includes undervoltage lockout (UVLO), overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown (TSD).
The ADP2311 operates over the −40°C to +125°C junction temperature range and is available in a 24-lead LFCSP package.
