Monolithic 1Amp DC:DC Step-down

Regulator

Features

• Integrated synchronous MOSFETs and current mode

controller

The EL7551 is an integrated,

synchronous step-down regulator with

output voltage adjustable from 1.0V to

• 1A continuous output current

• Up to 95% efficiency

3.8V. It is capable of delivering 1A continuous current at up

to 95% efficiency. The EL7551 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 EL7551 is

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

external components, the whole converter fits into a less

• 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 1.2MHz

• Oscillator synchronization possible

• Internal soft start

than 0.4 in area. The minimal external components and

small size make this EL7551 ideal for desktop and portable

applications.

The EL7551 is specified for operation over the -40°C to

+85°C temperature range.

• Over temperature protection

• Under voltage lockout

• 16-pin QSOP package
