Микросхемы и комплектующие ADP2116ACPZ-R7

Импульсный понижающий DC-DC стабилизатор , регулируемый, 2.75В-5.5В (Vin), 3A выход, 2МГц, LFCSP-32

The ADP2116ACPZ-R7 is a synchronous step-down DC-to-DC Regulator for use with point-of-load regulation applications. 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 2MHz. 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 performance signal chain circuits. The bidirectional synchronization pin is also configurable as a 90° out-of-phase output clock, providing the possibility for a stackable multiphase power solution.

• Optimized gate slew rate for reduced EMI
• External synchronization input or internal clock output

• Pulse skip mode with light loads or forced PWM operation
• Input undervoltage lockout (UVLO)
• Independent enable inputs and power-good outputs
• Overcurrent and thermal overload protection
• Programmable soft-start
• Up to 95% high efficiency
• ±1.5% Accurate reference voltage
