ADP2116ACPZ-R7

The ADP2116 is a versatile oneSynchronous step-down switching regulatorto meet a variety of customer point-of-load requirements. The two PWM channels can be configured as two independent outputs providing 3 A and 3 A (or 3 A and 2 A) respectively, or as a single interleaved output providing 6 A. To reduce input ripple current and input capacitance, the two PWM channels are offset by 180º. The ADP2116 offers high power efficiency and can be switched at frequencies up to 2 MHz. At light loads, the device can be set to operate in pulse-skipping mode for improved power efficiency or in forced PWM mode for noise-sensitive applications.

The slew rate of the ADP2116 is optimized to reduce electromagnetic emissions (EMI) to power sensitive, high performance signal chain circuitry. The switching frequency can be set to 300 kHz, 600 kHz, or 1.2 MHz, or synchronized to an external clock to minimize system noise. The bidirectional synchronization pin can also be configured as a 90º inverting output clock, enabling stackable multiphase power solutions.

The ADP2116 has an input voltage range of 2.75 V to 5.5 V; The fixed output voltage for each channel can be independently set with external resistors: 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, or 3.3 V. The resistor divider can also be used to set the output voltage to a minimum of 0.6 V. The device operates over the −40°C to +125°C junction temperature range.
