FSL156MRBN

The FSL156MRBN belongs to the ac dc converters, offline switchers category of Power Management Integrated Circuit (PMIC). It is a single-output control integrated circuit (IC) buck converter with an internal power switch. It has an integrated high-side MOSFET with a maximum current of 1.5A. It features a wide-input range of up to 32V and can deliver a regulated output voltage of 1.8V to 16V.

The FSL156MRBN allows the user to program various functions using the various input ports. It contains an enable pin to control the converter on and off, a voltage reference pin to set the output voltage, and an enable/disable input to control the IC’s internal power switch.

The FSL156MRBN is designed for bidirectional applications such as motor control, lighting control, and DC-DC power supply systems. It can also be used in AC-DC power supplies, uninterruptible power supplies (UPSs), etc.

The FSL156MRBN has two operating modes, the discontinuous conduction mode (DCM) and the continuous conduction mode (CCM). In DCM mode, the voltage across the inductor rises faster than the output voltage during the switching intervals, so it produces more ripple current than CCM. In CCM mode, the inductor current is continuous and the output voltage is better regulated.

The FSL156MRBN features various protections which include over voltage, under voltage, over current, and short-circuit protection. It also has an over temperature protection feature and a fault indicator LED.

The FSL156MRBN has a high efficiency and excellent load and line transient response. It features a fast current-limit protection and a proprietary adaptive peak current limit, which results in a faster response time and avoids output overshoot.

The FSL156MRBN supports a wide range of output voltages, allowing the user to select the desired voltage. It also has an adjustable current-limit function so the user can easily set the desired current limit.

The FSL156MRBN can operate over a wide temperature range of -40°C to +125°C with no derating. This feature makes it suitable for use in harsh environmental conditions.

The FSL156MRBN is a highly reliable, efficient and cost-effective PMIC. It is a suitable choice for various industrial, automotive, and consumer applications.
