RH5RH××1A/××2B/××3B SERIES APPLICATION MANUAL
The RH5RH XX1A/XX2B/XX3B series are PWM step‑up DC/DC converter ICs designed for battery‑powered equipment that require low ripple, low noise, and low supply current. The manual outlines the internal architecture, external component requirements, and performance specifications of the three IC variants.
Key sections include an outline of features, a block diagram, pin configuration tables, absolute maximum ratings, electrical characteristics, a selection guide for output voltage and driver options, and application hints for PCB layout and component selection.
| Typical Output Voltage (RH5RH301A) | 3.000 V |
|---|---|
