2.2A 32V Synchronous Rectified Step-Down Converter TD2776
General Description
Features
The TD2776 is a monolithic synchronous buck
regulator. The device integrates two 90mΩ
MOSFETs, and provides 2.2A of continuous load
current over a wide input voltage of 4.75V to 32V.
Current mode control provides fast transient
response and cycle-by-cycle current limit.
An adjustable soft-start prevents inrush current at
turn-on, and in shutdown mode the supply current
drops to 1µA.
This device, availablein an SOP8-PP package,
provides a very compact solution with minimal external
components.
2.2A Output Current Wide 4.75V to 32V Operating Input Range Integrated 90mΩ Power MOSFET Switches Output Adjustable from 0.923V to 30V Up to 93% Efficiency Programmable Soft-Start Stable with Low ESR Ceramic Output Capacitors Fixed 340KHz Cycle-by-Cycle Over Current Protection Input Under Voltage Lockout
Applications
