• 4.5V to 5.5V input voltage

• Adjustable output from 1V to 3.8V

• Cycle-by-cycle current limit

• Precision reference

• ±0.5% load and line regulation

• Adjustable switching frequency to

1MHz

• Oscillator synchronization

possible

• Internal soft start

The EL7562C is an integrated, synchronous step-down regulator with

output voltage adjustable from 1.0V to 3.8V. It is capable of delivering

2A continuous current at up to 95% efficiency. The EL7562C operates

at a constant frequency pulse width modulation (PWM) mode, making

external synchronization possible. Patented on-chip resistorless cur-

rent sensing enables current mode control, which provides cycle-by-

cycle current limiting, over-current protection, and excellent step load

response. The EL7562C is available in a fused-lead 16-pin QSOP

package. With proper external components, the whole converter fits

into a less than 0.5 in²area. The minimal external components and

small size make this EL7562C ideal for desktop and portable

applications.

The EL7562C is specified for operation over the -40°C to +85°C tem-

perature range.

• Over temperature protection

• Under voltage lockout

• 16-pin QSOP package
