RH5RH551A-T1-F - Brand New RICOH IC Chips
-
Description
The RH5RH××1A-T1-F is a step-up DC/DC converter integrated circuit (IC) designed for high efficiency and low ripple functioning. It is manufactured using complementary metal-oxide-semiconductor (CMOS) technology and belongs to the RH5RH××1A/××2B/××3B series of PWM step-up DC/DC converter ICs. The IC employs an oscillator, a driver transistor, a reference voltage unit, and an error amplifier, among other components. With only three external components, an inductor, a diode, and a capacitor, an ultra-low supply current can be achieved, making it a suitable device for battery-powered and low-power applications.
