GENERAL DESCRIPTION
BM1513/A consists of step-down switching
regulator with PWM control. These devices
include a reference voltage source, oscillation
circuit, error amplifier, internal PMOS and etc.
BM1513/A provides low-ripple power, high efficiency
and excellent transient characteristics. The PWM
control circuit is able to very the duty ratio linearly
from 0 up to 100%. This converter also contains
an error amplifier circuit as well as a soft-start
circuit that prevent s overshoot at startup. An
enable function, an over current protect function
and a short circuit protect function are built inside,
and when OCP or SCP happens, the operation
frequency will be reduced from 400KHz to 60KHz.
Also, an internal compensation block is built in to
minimum external component count.
These ICs can function as step-down switching
regulators. They serve as ideal power supply units
for portable devices when coupled with the SOP-8L
mini-package, providing such outstanding features
as low current consumption. Since this converter
can accommodate an input voltage of up to 18V, it
is also ideal when operating via an AC adapter.
