AN1201SM-TXL is a DC/DC switching regulator from the AN1201 series, a family of low-noise, highly efficient power management integrated circuits (PMICs) from Fairchild Semiconductor. The AN1201 series provides adjustable step-down DC/DC switching converters with output voltages ranging from 0.8V to 1.8V. The AN1201SM-TXL is specifically designed to deliver a full output powe at current draw up to 1A with a very low ripple noise. It also features the advanced low-dropout voltage linear VOUT setting, allowing it to achieve higher efficiency by providing adjustable output voltages at very low input voltages. The AN1201SM-TXL is especially suitable for powering advanced graphics processors, image sensors and other electronic components that require very low ripple noise.

The AN1201SM-TXL is a highly efficient DC/DC switching regulator. It operates at a very low switching frequency – 500kHz~1MHz, which helps to reduce EMI and further improve efficiency. Its wide input voltage range of 4.5V to 16V makes it suitable for a variety of different applications. The regulator also features built-in power limiting, over-temperature protection, and short circuit protection for better reliability. In addition, an external PGOOD pin monitors the load current, allowing for a more stable output voltage.

The AN1201SM-TXL supports positive or negative logic-level enable control, as well as low-voltage (1.5V) and high-voltage (3.3V) enable control. It can also operate in both continuous-conduction mode (CCM) and discontinuous-conduction mode (DCM). The regulator also features switch-mode power supply (SMPS) control timing, ensuring clean switching transitions to further reduce EMI.

The AN1201SM-TXL can be configured to provide either a fixed output voltage or a variable output voltage. When a fixed output voltage is desired, the VOUT pin can be tied to an external voltage reference — either a resistor-divider or an external reference voltage. When a variable output voltage is desired, the output voltage can be adjusted by connecting an external potentiometer to the VOUT pin. The AN1201SM-TXL also has a wide range of output current protection, allowing it to be used in applications that require large current draws.

The AN1201SM-TXL is a highly efficient, low-noise and reliable DC/DC switching regulator. It is suitable for a wide range of applications, including advanced graphics processors, image sensors and other electronic components that require very low ripple noise. The device\'s wide input voltage range, adjustable output voltage and wide current range make it suitable for a variety of applications. It is also a highly reliable option, as it features built in protection features, as well as SMPS control timing to ensure clean switching transitions.
