5V 6A 1.2MHz Synchronous Boost Converter

EC9288

General Description

Features

The EC9288 is a synchronous rectifier, fixed switching

frequency (1.2MHz typical), and current-mode step-up

regulator. The device allows use o f small inductors and

output capacitors for USB devices. The current-mode control

scheme provides fast transient response and good output

voltage accuracy.

● 92%EffiicencySynchronousBoostConverter With

1000-mA Output Current From 1.8V Input

● Stable with Low ESR Output Capacitors

● Fixed 1.2MHz Oscillator Frequency

● Low EMI Converter (Integrated Anti-Ringing Function)

● Low Battery Output

At light loads, the EC9288 will automatically enter in Pulse

Frequency Modulation (PFM) operation to reduce the

dominant switching losses. During PFM operation, the IC

consumes very low quiescent current and maintains high

efficiency over the complete load range. The EC9288 also

includes current-limit and over temperature shutdown to

prevent damage in the event of an output overload.

The EC9288 is available in SOP-8(Exposed Pad) packages.

● Integrated Power Save Mode Operation to Improve Light

Load Efficiency

● On load startup

● Automatic restart after protection

● Load Disconnected During Shutdown

● Output Current-Limit Protection

● Over Temperature Protection

● Under Voltage Protection

● Enable/Shutdown Function

● Available in SOP-8(Exposed Pad) Packages

● Lead Free and Green Devices Available( RoHS Compliant)

Applications

● Power Bank

● Tablet

● Portable Equiment
