The APW7066 is a dual synchronous buck PWM controller and one linear controller with high precision internal reference voltage to offer accurate outputs. The product has various features and characteristics, such as two synchronous buck converters and a linear regulator, VIN range up to 12V, three outputs with independent soft-start and enable functions, etc.
The APW7066 integrates two synchronous buck converters and one linear regulator with high-precision internal reference voltages. The device is designed to drive N-channel MOSFETs in a synchronous buck topology or an external N-channel MOSFET for the linear controller, requiring 12V and 5V power supplies.
| Input Voltage Range (VCC12) | up to 12V |
|---|---|
| Reference Voltage VOUT1 and VOUT3 | 0.6V |
| Reference Voltage VOUT2 | 3.3V |
| System Accuracy | ±0.8% |
| Operating Temperature Range | 0 to +70 °C |
| Maximum Junction Temperature | +150 °C |
| Oscillator Frequency (Typical) | 300kHz |
| Programmable Frequency Range | 70 kHz to 800kHz |
Pulling the SS/EN pin below 1V disables the regulator.
The PGOOD pin goes high when all SS/EN pins exceed 3.3V and no faults are detected, indicating regulators are ready.
