DC-DC преобразователи интегральные TPS54327DDA

Импульсный понижающий DC-DC стабилизатор , регулируемый, 4.5В-18В (Vin), 760мВ-7В, 3А, PPAD-8

The TPS54327DDA is a single synchronous Step-down Switcher with integrated FET. The TPS54327 device is an adaptive on-time D-CAP2™ mode synchronous buck converter. TheTPS54327 enables system designers to complete the suite of various end equipment's power bus regulators with low component count and low standby current solution. The main control loop for the TPS54327 uses the D-CAP2 mode control which provides a fast transient response with no external compensation components. The TPS54327 also has a proprietary circuit that enables the device to adopt to both low equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP and ultra-low ESR ceramic capacitors. The device operates from 4.5 to 18V VIN input. The output voltage can be programmed between 0.76 and 7V. The device also features an adjustable soft-start time.

• D-CAP2™ mode enables fast transient response
• Low-output ripple and allows ceramic output capacitor
• Highly efficient integrated FETs optimized for lower duty cycle applications
• High initial bandgap reference accuracy
• Adjustable soft-start
• Prebiased soft-start
• Cycle-by-cycle overcurrent limit
• High efficiency, <10µA at shutdown
