General Description
RZ1510 consists of step-down switching regulator
with PWM control. These devices include a
reference voltage source, oscillation circuit, error
amplifier, internal PMOS and etc.
RZ1510 provides low-ripple power, high
efficiency,and excellent transient characteristics.
The PWM control circuit is able to vary 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 prevents 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 300KHz
to 30KHz. Also, an internal compensation block is
built in to minimum external component count.
With the addition of an internal P-channel Power
MOS, a coil, capacitors, and a diode connected
externally, these ICs can function as step-down
switching regulators. They serve as ideal power
supply units for portable devices when coupled
with the SOP8 mini-package, providing such
outstanding features as low current consumption.
Since this converter can accommodate an input
voltage up to 20V, it is also suitable for the
operation via an AC adapter.
