The LTC3835EDHC-1#TRPBF belongs to the category of PMIC - Voltage Regulators - DC DC Switching Controllers. This product is a flexible DC-DC Switching Controller integrated with a Synchronous Switching Regulator and a Linear Regulator. It is a monolithic integrated solution intended to reduce external component count and board area while delivering high performance, low input voltage stress and high power conversion efficiency. It also offers a wide variety of output current capabilities and output voltage options.

The LTC3835EDHC-1#TRPBF is suitable for high efficiency code running or low current standby applications in a wide variety of applications. It is particularly ideal for systems that require multiple power rail voltages, such as laptop computers, wireless communications, tablets, thin-clients, ultra-mobile PCs, industrial PCs, and embedded systems.

The main application field of the LTC3835EDHC-1#TRPBF includes computing, embedded and network system, audio video and lighting control systems, industrial equipment, and application specific products. Its primary benefit is the flexibility it provides to support switching off of lower power rails during low power conditions and disabling of output rails which are not needed. In addition, it supports manually programming power good flags and/or fault flags for each output voltage. At the same time, it can provide various fault handling conditions to eventually protect the system.

The working principle of the LTC3835EDHC-1#TRPBF is based on a Synchronous Switching Regulator and a Linear Regulator. The Synchronous Switching Regulator takes an unregulated DC input voltage, such as a battery or a wall adapter, and converts it into a stable DC output voltage. The Synchronous Switching controller also supports as many as four switching voltage regulators. All four switching regulators can be in a single phase, dual phase, triple phase, or quad-phase operation. The number of synchronization and current fold back is programmable according to the switch configuration. The Linear Regulator is used to create additional output voltages by regulating a single input voltage and outputting multiple regulated voltages. The buck converter, commonly referred to as a constant voltage converter, is also controllable to ensure a stable output.

In addition, the controller is designed for overriding the automatic system control of the DC-DC converters and provides manual access to the system. The manual pins are shorted out and the manual signal will override the system control signal. This function enables the user to manually control the Buck Converter, the PWM Controllers, and the Pulse Width Controllers. It also allows manual adjustment of the Automatic Mode, which provides the user with an override or no override option. The Automatic Mode also allows for power good and fault flag signals for output voltages, allowing monitoring of external power supplies, under voltage lockouts and frequency synchronization.

The LTC3835EDHC-1#TRPBF is a multi-output DC-DC converter heavily dependent upon external components to produce the desired DC voltage and current. The integrated Linear Regulator gives users an extensive voltage range while the Synchronous Switching Regulator offers efficient power conversion. Additionally, the manual access to the system provides flexibility in user control and monitoring. This combination of features makes the LTC3835EDHC-1#TRPBF suitable for use in many different applications.
