MB3785A General Description
The MB3785A is a PWM-based 4-channel switching regulator controller featuring high-precision, high-frequency capabilities. All of the four channels of circuits allow their outputs to be set in three modes: step-down, step-up, and inverted. The third and fourth channels are suited for DC motor speed control.
The triangular-wave oscillation circuit accepts a ceramic resonator, in addition to the standard method of oscillation using an RC network.
MB3785A Maximum Ratings
(Ta = +25°C)
| Rating | Symbol | Conditions | Rating | Unit |
| Power supply voltage | VCC | — | 20 | V |
| Control input voltage | VICTL | — | 20 | V |
| Power dissipation | PD | Ta≤ +25°C | 550* | mW |
| Operating ambient temperature |
TOP | — | –30 to 85 | °C |
| Storage temperature | Tstg | — | –55 to 125 | °C |
WARNING: Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded.
Functional operation should be restricted to the conditions as detailed in the operational sections of
this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
