File Size : 116 KB Manufacturer:FREESCALE Description: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 stretch- es the duty cycle to >99.5% for low-dropout design. Unlike conventional step-down regulators using a p- channel 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 pack- age 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 out- put, 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 fea- tures output overvoltage protection. These controllers also feature lossless high-side peak inductor current sensing, adjustable current limit, and hiccup-mode short-circuit protection. Switching fre- quency 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 com- pensation scheme to give the user ample flexibility to optimize for cost, size, and efficiency.
