MAX8597, MAX8598, MAX8599 Low-Dropout, Wide-Input-Voltage, Step-Down Controllers

The MAX8597 MAX8598 MAX8599 voltage-mode PWM Step-down controllers are designed to operate from a 4.5V to 28V input supply and generate output voltages down to 0.6V. A proprietary switching algorithm stretches the duty cycle to >99.5% for low-dropout design. Unlike conventional Step-down Regulators using a pchannel high-side MOSFET to achieve high duty cycle, the MAX8597 MAX8598 MAX8599 drive n-channel MOSFETs resulting in high efficiency and high-current-capability designs. The MAX8597 is available in a 20-pin thin QFN package and is designed for applications that use an Analog signal to control the output voltage with an adjustable offset, such as DC fan-speed control. This is achieved with an internal uncommitted Operational Amplifier The MAX8597 is also targeted for tracking output-voltage applications for chipsets, ASIC and DSP cores, and I/O supplies. The MAX8598 MAX8599 are available in a 16- pin thin QFN package and do not have the uncommitted Operational Amplifier reference input, and reference output, but offer an open-drain, power-OK output. The MAX8597 MAX8598 MAX8599 allow startup with prebias voltage on the output for applications where a backup supply or a tracking device may charge the output capacitor before the MAX8597 MAX8598 MAX8599 are enabled. In addition, the MAX8599 features output overvoltage protection. These controllers also feature lossless high-side peak inductor current sensing, adjustable current limit, and hiccup-mode short-circuit protection. Switching frequency is set with an external resistor from 200kHz to 1.4MHz. This wide frequency range combined with a wide-bandwidth error Amplifier enables the loop compensation scheme to give the user ample flexibility to optimize for cost, size, and efficiency.
