Working Principle

The LT1767EMS8E-3.3#TRPBF operates in pulse-width modulation (PWM) mode, which is a type of switch-mode regulator. In this type of regulator, an oscillator is used to generate a train of pulses at a fixed frequency, with the pulse width modulated accordingly to maintain a stable output voltage. The output voltage is adjusted by varying the duty cycle (proportion of “on” time versus “off” time). The frequency of operation is set by the user in order to minimize output ripple and minimize size of the filter components.

The LT1767EMS8E-3.3#TRPBF also features a power-saving “Burst Mode” operation which reduces quiescent current during light-load operation. This mode is enabled either automatically by the built-in current feedback loop or manually by the user via a logic control pin. When Burst Mode is enabled, the switching regulator reduces the duty cycle of the PWM output to reduce ripple, resulting in lower overall power consumption. The Burst Mode hysteresis is adjustable so that the switching regulator can be optimized for the specific application.

To efficiently step down the input voltage, the LT1767EMS8E-3.3#TRPBF switching regulator also uses a low on-resistance synchronous rectifier, so that the device can reach up to 97% efficiency. Furthermore, the switching regulator integrates a linear regulator to further optimize efficiency while keeping noise to a minimum.

The LT1767EMS8E-3.3#TRPBF switching regulator also includes a rich set of protection features, such as adjustable cycle-by-cycle current limiter, over-voltage and under-voltage lockout, and thermal shutdown. All these features ensure minimum risk of damage when operating in adverse conditions.

The LT1767EMS8E-3.3#TRPBF switching regulator is a reliable, efficient, and versatile device for a wide range of applications which require high efficiency and small size. Its wide input voltage range, integrated power switch, and various features make it well suited for automotive, industrial and mobile equipment.
