The ADP2114 is a highly versatile, synchronous step-down, switching regulator that can be configured to satisfy a wide range of customer point of load requirements. The two PWM channels can be configured to deliver independent outputs at 2 A and 2 A (or 3 A/1 A) or can be configured as a single interleaved output capable of delivering 4 A. The two PWM channels are 180º phase shifted to reduce input ripple current and reduce input capacitance.

The ADP2114 provides high efficiency performance at full loads, enabling high switching frequencies at up to 1.2 MHz. At light loads, the ADP2114 can be set to operate in pulse skip mode for higher efficiency or in forced PWM mode to reduce EMI.

The device is designed with an optimized gate slew rate to reduce ENI emissions, allowing the device to supply sensitive, high performance signal chain applications. The frequency can be set to 300 kHz, 600 kHz and 1.2 MHz and can be synchronized to an external clock signal, minimizing the system noise between converters. The bidirectional synchronization pin is also configurable as a 90º out-of-phase output clock, providing the possibility for a stackable multiphase power solution. The ADP2114 input voltage range is from 2.75 V to 5.5 V, and it converts to fixed outputs 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. Using a resistor divider, it is also possible to set the output voltage as low as 0.6 V. The ADP2114 operates over the −40°C to +125°C junction temperature range.
