TD2776A Datasheet | Techcode

Description Features The TD2776A is a monolithic synchronous buck - 2.2A Output Current regulator. The device integrates two 90mΩ - Wide 4.75V to 32V Operating Input Range MOSFETs, and provides 2.2A of continuous load - Integrated 90mΩ Power MOSFET Switches current over a wide input voltage of 4.75V to 32V. - Output Adjustable from 0.923V to 30V Current mode control provides fast transient - Up to 93% Efficiency response and cycle-by-cycle current limit. - Programmable Soft-Start An adjustable soft-start prevents inrush current at - turn-on, and in shutdown mode the supply current Stable with Low ESR Ceramic Output Capacitors drops to 1µA. - Fixed 600KHz Frequency This device, availablein an SOP8-PP package, - Cycle-by-Cycle Over Current Protection provides a very pact solution with minimal external - Input Under Voltage Lockout ponents. Applications - Distributed Power Systems - Networking Systems - FPGA, DSP, ASIC Power Supplies - Green Electronics/ Appliances - Notebook puters Package Types October, 20, 2010. Figure 1.

Techcode® 2.2A 32V Synchronous Rectified Step-Down Converter Pin Configurations Pin Description Figure 2 Pin Configuration of TD2776A(Top View) Pin Number Pin Name Description 1 BS High-Side Gate Drive Boost Input. BS supplies the drive for the high-side N-Channel MOSFET switch. Connect a 0.01µF or greater capacitor from SW to BS to power the high side switch. 2 IN Power Input. IN supplies the power to the IC, as well as the step-down converter switches. Drive IN with a 4.75V to 32V power source. Bypass IN to GND with a suitably large capacitor to eliminate noise on the input to the IC. See Input...
