降压型DC-DC
功能特点
产品名称:降压型DC-DC
产品型号:RM1410
产品描述:
RM1410 consists of step-down switching regulator with PWM control. These devices include
a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc.
RM1410 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%. 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 380KHz to 35KHz. 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 SOP–8L mini-package, providing such outstanding features as low current consumption. Since this converter can accommodate an input voltage up to 15V, it is also suitable for the operation via an AC adapter.
