MAX8667/MAX8668 1.5MHz Dual Step-Down DC-DC Converters with Dual LDOs and Individual Enables
The MAX8667 and MAX8668 are dual step‑down DC‑DC converters that integrate low‑dropout linear regulators. They are designed for low‑voltage microprocessors, DSPs, and portable devices, offering adjustable output voltages and high efficiency in a 3 mm × 3 mm thin QFN package.
Key features include individual enable pins for each regulator, 600 mA output on OUT1, 1.2 A on OUT2, low quiescent current (100 µA no‑load), and operation over an extended temperature range of –40 °C to +85 °C.
| Output current OUT1 | 600 mA |
|---|---|
| Output current OUT2 | 1200 mA |
| Adjustable output voltage (MAX8668) | 0.6 V – 3.3 V |
| Package size | 3 mm × 3 mm thin QFN, 16‑pin |
| Operating temperature range | –40 °C to +85 °C |
The LDO regulators accept an input voltage range from 1.7 V to 5.5 V.
The device is supplied in a 16‑pin thin QFN package.
