.LTC3626IUDC#PBF application field and working principleThe LTC3626IUDC#PBF, manufactured by Linear Technology Corporation, is a highly integrated synchronous DC-DC converter. It has a wide range of applications, including powering DSPs, FPGAs, A/D converters, ASICs, wireless devices and microprocessor cores. Additionally, the part is optimized for extended temperature range, making it suitable for operation in harsh environmental conditions.
The LTC3626IUDC#PBF is a buck switching regulator, meaning that it is designed to step down the output voltage from a higher input voltage. It can achieve high efficiency and fast transient response because of its integrated synchronous power conversion technology and its low-on-resistance MOSFET switches. The buck regulator also features programmable frequency, and an integrated high-side switch can be used with it.
The LTC3626IUDC#PBF includes several protections, such as over temperature protection, cycle-by-cycle current limit, and short-circuit protection. It also has a maximum duty cycle of 99% allowing for a wide range of input voltage. The device also has a foldback current limit feature, which allows for a lower current limit during light loads.
The synchronous design of the LTC3626IUDC#PBF makes it superbly efficient with up to 93% efficiency, depending on the load and input voltage. The device also features an internal compensation scheme that reduces the need for external components, and the integrated switching MOSFET reduces board space and component count.
The LTC3626IUDC#PBF also includes a power good output, which indicates the output voltage and can be used with a supervisor IC to ensure that the output voltage is within the programmed operating range. Additionally, the device can tolerate up to 2 millisecond input voltage transients, such as those created by hot-plugging or ESD discharge.
The LTC3626IUDC#PBF offers flexible voltage programming, which is accomplished through the use of external resistors and a programmable soft-start feature is also included. The device can be configured to provide output voltages from 0.6V to 5.5V.
In summary, the LTC3626IUDC#PBF is a highly integrated synchronous DC-DC converter, offering high efficiency, fast transient response and flexible voltage programming. Its low-on-resistance MOSFET switch and integrated high-side switch make it well suited for powering high current devices, such as FPGAs and A/D converters, and the part is optimized for extended temperature range, making it suitable for use in tough environments.
