2.2A Output Current
The TD2776(A) 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.
Wide 4.75V to 32V Operating Input Range
Integrated 90mΩ Power MOSFET Switches
Output Adjustable from 0.923V to 30V
Up to 93% Efficiency

Current mode control provides fast
response and cycle-by-cycle current limit.
transient
Programmable Soft-Start
An adjustable soft-start prevents inrush current at
turn-on, and in shutdown mode the supply current
drops to 1µA.
Stable with Low ESR Ceramic Output Capacitors
• Fixed 340KHz(TD2776)/600KHz(TD2776A)
Frequency
This device, availablein an SOP8-PP package,
provides a very compact solution with minimal external
components.
