Configurable, Dual 3 A/Single 6 A, Synchronous, Step-Down DC-to-DC Regulator
The ADP2116 is designed with an optimized slew rate to reduce EMI emissions, allowing the device to power sensitive, high perfor-mance signal chain circuits. The switching frequency can be set to 300 kHz, 600 kHz, or 1.2 MHz, or it can be synchronized to an external clock that minimizes the system noise. The bidirectional synchronization pin is also configurable as a 90° out-of-phase output clock, providing the possibility for a stackable multiphase power solution.
The ADP2116 input voltage range is from 2.75 V to 5.5 V and can convert to a fixed output of 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, or 3.3 V that can be set independently for each channel using external resistors. If a resistor divider is used, the output voltage can be set as low as 0.6 V. The ADP2116 operates over the −40°C to +125°C junction temperature range.Applications
