ADP2114ACPZ-R7

ADP2114 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 2A and 2A (or 3A/1A) or can be configured as a single interleaved output capable of delivering 4A. The two PWM channels are 180º phase shifted to reduce input ripple current and to reduce input capacitance. It provides high efficiency and operates at switching frequencies of upto 2MHz. At light loads, this device can be set to operate in pulse skip mode for higher efficiency or in forced PWM mode to reduce EMI. It is designed with an optimized gate slew rate to reduce EMI emissions, allowing it to power sensitive, high performance signal chain circuits. It is used in application such as point of load regulation, telecommunications and networking systems, consumer electronics, industrial and instrumentation, medical etc.
