EL7562
Monolithic 2Amp DC-DC Step-Down
Regulator
The EL7562 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 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
than 0.5 in
2
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.
