Flyback Controllers Operate from -55°C to 150°C Junction Temperature
Linear Technology announced high reliability military temperature (MP) grade versions of the LTC3803/-3/-5 current mode flyback controllers in the tiny 6-pin ThinSOT™ package. These devices are specified and are 100% production tested over a junction temperature range of -55°C to 150°C. The input and output voltage ranges of LTC3803/-3/-5-based power supplies are limited only by external components, enabling wide-input-voltage and high-input-voltage applications commonly found in industrial, telecom, military and automotive settings.
The constant 200kHz or 300kHz operating frequency is maintained down to very light loads, minimizing low frequency noise generation over a wide range of load current. An integrated soft-start function reduces inrush current and output voltage overshoot. A 100mV current sense threshold allows the use of a small current sense resistor to maintain high efficiency. An LTC3803/-3/-5-based power supply does not require any minimum output load for stable operation. An internal shunt regulator allows the LTC3803/-3/-5 to be powered simply from a high input voltage through a series resistor. In wide-Vin-range applications where this isn’t feasible, the LTC3803 and LTC3803-3 feature a wide hysteresis undervoltage lockout that enables efficiency-enhancing micropower startup and bootstrap biasing techniques.
