Product Description

Product Details
The ADP2116 is a versatile, synchronous, step-down switching regulator that satisfies a wide range of customer point-of-load requirements. The two PWM channels can be configured to deliver independent outputs at 3 A and 3 A (or at 3 A and 2 A) or can be configured as a single interleaved output capable of delivering 6 A. The two PWM channels are 180° phase shifted to reduce input ripple current and input capacitance.
The ADP2116 provides high efficiency and can operate at switching frequencies of up to 2 MHz. At light loads, the ADP2116 can be set to operate in pulse skip mode for higher efficiency or in forced PWM mode for noise sensitive applications.
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.
