The LTC1261LCS8#PBF is a high-power low-loss, monolithic synchronously rectified, DC to DC switch-mode power supply (SMPS) integrated circuit (IC) from Linear Technologies. It integrates all the components needed to produce a regulated output voltage with high efficiency and low power losses across a wide input voltage range. This device is designed for use in applications that require very high power supplies, such as communications, computing, and industrial applications, which require efficient AC-to-DC conversion and/or DC-to-DC voltage conversion.

The LTC1261LCS8#PBF is a synchronous rectifier DC-DC converter, which improves efficiency and reduces power losses compared to traditional rectifier topologies. The device uses a pair of high-definition independent PMOS power transistors to switch-mode from AC to DC, resulting in high efficiency and power loss reduction even at high switch frequencies. A low-noise isolation transformer at the output of the device helps reduce electromagnetic interference (EMI) and provides an isolated output voltage.

The LTC1261LCS8#PBF features a wide input voltage range of 7 to 56V and a wide output voltage range of 0.6 to 5.5V. The device has a switching frequency range from 200kHz to 500kHz and a single power supply operating temperature range of –40°C to +85°C. It is rated for continuous output current of up to 10A and can handle load capacitances up to 100µF. The wide input voltage range and the low-noise isolation transformer make the LTC1261LCS8#PBF ideal for applications that require low-noise isolated AC-DC conversion or high-power DC-DC voltage conversion.

The LTC1261LCS8#PBF features integrated monitoring and control circuitry that allows it to be operated in two modes, continuous and pulse width modulated (PWM). In continuous mode, the converter maintains a steady output voltage regardless of input voltage variations, line regulation over the input voltage range, and load variations. In PWM mode, the output voltage is controlled by varying the duty cycle of the switch node, allowing the device to adjust the output voltage over a wide range. This allows the device to be used in applications with high input voltage variations and high output currents.

The LTC1261LCS8#PBF also features built-in clamping for output overvoltage and current-limit protection for high-current applications. The device can be protected from overload and short-circuit conditions with an adjustable over-current limit that is monitored on-chip. Additional features include fault and enable inputs, a thermal shutdown circuit, an internal soft start circuit, and a synchronized frequency.

The LTC1261LCS8#PBF is a highly efficient, low-power loss integrated circuit that is ideal for applications that require high power supplies and efficient AC-to-DC conversion or DC-to-DC voltage conversion. It features a wide input voltage range, a wide output voltage range, a single power supply operating temperature range, an adjustable over-current limit, and integrated monitoring and control circuitry. It is suitable for a variety of applications, such as communications, computing, and industrial applications.
