SIP12108ADMP-T1GE4 is DC-DC switching voltage regulator, based on Hot Swap Technology, which is designed for controlling voltage supplies and on-board logic power supplies of high-end servers, servers, high-end switches, routers and other equipment. Its features include: good transient response, low output noise, good output voltage stability and small size.

SIP12108ADMP-T1GE4 application field lies in the server and storage industry. They are perfect partner for DRAM and flash memory power supplies, providing the stability and the flexibility necessary for its operation. Its wide input voltage range and up to 8 outputs make it ideal for high power applications that require an unusually high regulator current density. Moreover, it is also widely applied to broadband routers, switches and other communication equipment.

This DC-DC switcher consists of an integrated synchronous buck regulator controller and a pair of high- and low-side MOSFETs, which are configured in a full-bridge layout. By synchronizing the gate drive of the two MOSFETs, the full-bridge power stage can be utilized for efficient energy conversion. The controller, which is designed with a hysteretic current control loop, is capable of fast transient response and excellent loop stability. As a result, the datasheet claims that each regulator can source up to 21A of continuous current.

Furthermore, the basic operation of the SIP12108ADMP-T1GE4 also involves voltage supervision and under-voltage lockout (UVLO). If the input voltage is lower than the trip point of the UVLO, then the regulator will be forced into a low power state or disabled by holding its PWM signal low. This feature prevents the system from working where the input supply is unsafe.

The SIP12108ADMP-T1GE4 was designed with low output noise in mind, making it possible to deliver responsive, non-overwhelming power. Its integrated power stage uses synchronous rectification to maximize efficiency, while an internal loop compensation circuit, known as ‘programmable line feed forward’ (PLFF), reduces output noise significantly. As a result, the device works with very little output noise, even at high output currents. Moreover, the regulator also features a peak current supporting circuit that can minimize the voltage drop due to a sudden current surge.

The SIP12108ADMP-T1GE4 also has excellent output voltage stability thanks to its dynamic voltage positioning (DVP) technology. It progressively optimizes the input-output conversion ratio by dynamically assigning the internal resistors, making sure the output voltage maintains a constant level. Moreover, this technology also accurately tracks the voltage change of the output voltage caused by external factors, and compensates for it accordingly.

In summary, the SIP12108ADMP-T1GE4 is an excellent choice for controlling voltage supplies and on-board logic power supplies of high-end servers, servers, high-end switches, routers and other equipment, due to its good transient response, low output noise, good output voltage stability, excellent performance, and small size. With its synchronous buck regulator controller, MOSFETs, power stage and other features, it is able to provide high-efficiency and long-term stability in even the most demanding applications.
