The ZXLD1371QESTTC product is a critical component of Power Management ICs (PMICs) used in LED drivers. This device, available from Diodes, Incorporated, is a 16V, 40mA, N-Channel, low voltage FET, SMPS controller and is suitable for portable battery powered applications. The device provides a low side FET drive for external synchronized switch-mode power supply (SMPS) topologies. It offers flexibility for applications such as AC/DC, DC/DC, white LED drivers, and digital LCD and DLP TV power supplies. Furthermore, it includes both active-clamp and phase-shift based topologies.

The low side drive FET and charge pump features of the ZXLD1371QESTTC are the primary features that make it suitable for LED driver applications. Its low side FET drive allows the low voltage FET to be controlled directly by the ZXLD1371QESTTC without any additional circuitry or components. This makes the device suitable for applications such as white LED drivers that require a low sided FET. The charge pump feature allows the device to regulate the LED current in response to varying supplies or load conditions. This makes the device ideal for applications such as mobile device displays or small LCD TVs that require a highly efficient and reliable power supply design. Additionally, the device includes an integrated soft-start circuit which reduces inrush current during start up.

The ZXLD1371QESTTC is characterized by its synchronous buck current-mode control and can be configured for buck, boost, buck/boost, or flyback topologies. Its current-sense architecture allows for current-mode control and makes the device ideal for applications that require accurate current regulation and fast response time. Additionally, it includes both fast and slow soft-start circuitry which provides smooth startup and prevents complications arising from abrupt current changes. It also helps prevent overvoltage and current limit trips due to the changing load conditions during startup. The device is also characterized by its current-mode control with leading edge modulation (LEM) and can be used with voltage or current mode control topologies depending on requirements.

The device features low power dissipation, a high efficiency drive stage, an adjustable 6V pre-bias current sense/valley voltage thresholds, and an adaptive pre-bias current limit feature. All these features help ensure a reliable and efficient power supply design that meets application voltage and current requirements. In addition, the device includes a thermal shutdown protection feature that prevents it from damage due to overtemperature. It offers short circuit protection (SCP), under voltage lock out (UVLO), and lead-free package options, making it suitable for various kinds of applications. Lastly, the device has a wide operating temperature range of -40 to +85°C, making it suitable for both commercial and industrial applications.
