The LTC1435CG#PBF is a DC-to-DC switching controller from the PMIC – Voltage Regulators – DC DC Switching Controllers family and is designed to help design engineers easily find the ideal solution for a variety of applications. The chip is an ideal companion for PFC pre-regulators, DC/DC converters, LED lighting dimming, electronic ballasts and other power supplies, providing fast load transient response for load step and dynamic load current changes.

The LTC1435CG#PBF DC-to-DC switching controllers provide excellent efficiency and improved accuracy while using a minimum number of external components. The LTC1435CG#PBF works in a Lossless Pulse Width Modulation (LPWM) mode with Pulse Frequency Modulation (PFM) being used under light load conditions to ensure high efficiency over the full load range. The LTC1435CG#PBF features programmable current limit, minimum on-time, and under-voltage lockout (UVLO) to ensure protection in case of overload, short-circuit and low input voltage.

The LTC1435CG#PBF integrated non-synchronous boost controller employs a totem pole drive circuit to reduce the instantaneous current consumption during start-up and provides a low-noise, low-ripple output. The output voltage is adjustable from 4V to 36V, and can handle up to 25W output power in SOT-23-5 or four-pin TO-263 package. Engineers can also integrate external powermosfet transistor to the LTC1435CG#PBF in order to increase the output power up to 45W.

The LTC1435CG#PBF DC-to-DC switching controller also provides a "low loss" PFC with voltage mode control. The voltage reference accuracy is adjustable up to 1% with no external hard to get components. The PFC also features integrated soft start and adjustable maximum on-time. The flexible loop compensation allows adjustable corner frequencies, as well as variable gain and phase margin to reduce EMI or improve stability.

The LTC1435CG#PBF DC-to-DC switching controller further offers external PWM mode control and current mode regulation, as well as a wide variety of operating and shutdown modes. This allows for better load transient response, improved accuracy and superior system performance. The device also supports frequency dithering with spread spectrum modulation, to reduce system EMI. The LTC1435CG#PBF features a wide voltage range, up to 24V and is available in SOT-23-5 and four-pin TO-263 packages.

In conclusion, the LTC1435CG#PBF DC-to-DC switching controllers are ideal solutions for a variety of applications. It offers excellent efficiency, improved accuracy with a minimum number of external components and a variety of operating and shutdown modes. With non-synchronous boost controller, voltage mode control and programmable current limit, the LTC1435CG#PBF ensures protection in case of overload, short-circuit and low input voltage. The LTC1435CG#PBF is a perfect choice for designers looking for a solution to their DC-to-DC switching needs.
