Monolithic 2Amp DC-DC Step-Down

Regulator

Features

• Integrated synchronous MOSFETs and current mode

controller

The EL7562 is an integrated,

synchronous step-down regulator with

• 2A continuous output current

• Up to 95% efficiency

output voltage adjustable from 1.0V to

3.8V. It is capable of delivering 2A continuous current at up

to 95% efficiency. The EL7562 operates at a constant

frequency pulse width modulation (PWM) mode, making

external synchronization possible. Patented on-chip

resistorless current sensing enables current mode control,

which provides cycle-by-cycle current limiting, over-current

protection, and excellent step load response. The EL7562 is

available in a fused-lead 16-pin QSOP package. With proper

external components, the whole converter fits into a less

• 3.3V or 5V nominal 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

than 0.5 in area. The minimal external components and

small size make this EL7562 ideal for desktop and portable

applications.

The EL7562 is specified for operation over the 0°C to +70°C

temperature range.

• Over-temperature protection

• Under-voltage lockout

• 16-pin QSOP package
