The LTC1436AIGN#PBF is a point-of-load (POL) DC/DC synchronous buck step-down switching controller IC from Linear Technologies. It is typically used to produce a constant power or voltage output from an adjustable input. When used as an adjustable DC/DC step-down controller, the LTC1436AIGN#PBF provides user friendly, flexible power sequencing and control for a wide variety of applications including servers, routers, switches, printers, video and audio systems, embedded systems, and portable devices.

The LTC1436AIGN#PBF belongs to the family of PMIC – Voltage Regulators – DC/DC Switching Controllers. PMIC stands for Power Management Integrated Circuits. These integrated circuits are used to insure optimal usage of the energy provided by batteries or other power sources. Their task is to regulate and control the power flow between the source and the load, protect the system in the case of short circuit and thermal overload, monitor the battery charge, protect the system from over voltage or over current and this list could go on and on. Voltage Regulators are part of the Power Management family and they are specifically used to maintain a certain voltage level. In this case, DC/DC Switching Controllers are used to provide conversion from one DC voltage to another, either synchronously or asynchronously.

The LTC1436AIGN#PBF is a CMOS synchronous buck step-down controllers with integrated Peak Current Mode MOSFET drivers. It is designed for applications such as telecom converters, distributed power systems and point-of-load (POL) applications from 6V or 12V inputs. It provides user friendly, flexible power sequencing and control, precise temperature sensing and closed loop system optimization. It also features a precise 0.5% internal reference, on-board power limiting, programmable soft-start, current-mode control and a low start-up current. The device also features an output gray-scale PWM mode for precise current sharing.

The working principle of the LTC1436AIGN#PBF is to use pulse width modulation (PWM) to control the voltage output of the device. The PWM duty cycle is controlled by the duty cycle signal from its internal clock circuit. The duty cycle signal is generated from the feedback signal from the output voltage sense. The duty cycle determines the magnitude of the voltage output. The current output is controlled by the current gain circuit, which is integrated into the PWM control block. The current gain circuit senses the output current and adjusts the PWM duty cycle according to the input voltage, output voltage, and the current sensing resistor value. The PWM pulse is then output to the external MOSFET to switch on and off the power converter, thereby providing the constant power or voltage output.

The LTC1436AIGN#PBF is a versatile step-down switching controller which is ideal for use in a variety of applications such as servers, routers, switches, printers, video and audio systems, embedded systems, and portable devices. Its integration of precision 0.5% internal references, on-board power limiting, programmable soft-start, and current-mode control make it a very flexible solution for a wide range of pol applications from 6V and 12V input sources. The LTC1436AIGN#PBF is a great choice for designers looking to optimize the power management of their applications.
