Product Overview
LT3844 is a DC/DC controller used for medium power, low part count, high efficiency supplies. It offers a wide 4V to 60V input range (7.5V minimum start-up voltage) and can implement step-down, step-up, inverting and SEPIC topologies. An internal high voltage bias regulator allows for simple biasing. Additional features include current mode control for fast line and load transient response; programmable fixed operating frequency that can be synchronized to an external clock for noise sensitive applications; a gate driver capable of driving large N-channel MOSFETs; a precision undervoltage lockout function; 10µA shutdown current; short-circuit protection and programmable soft-start function. It is used in applications such as industrial power distribution, 12V and 42V automotive and heavy equipment, high voltage single board systems, distributed power systems, avionics, telecom power etc.
- Programmable undervoltage lockout
- Internal high voltage regulator for gate drive
- Thermal shutdown, current limit unaffected by duty cycle
- Reference accuracy is ±1.3%
- VIN supply current is 20µA typical at (VCC
9V, TA = 25°C, VIN = 20V) - Operating frequency is 300KHz typical at (TA = 25°C, VIN = 20V)
- Operating junction temperature is -40°C to 125°C
- Package style is 16-lead plastic TSSOP
