The LTC3810 from Linear Technology is a high input-voltage synchronous step-down switching regulator controller that can directly step down voltages from 100 V to output voltages ranging from 0,8 V to 93% of VIN. This single inductor design eliminates the need for a transformer. The device employs a constant-on-time valley-current-mode control architecture to deliver very low duty cycles, and extremely fast transient response with accurate cycle-by-cycle current limit, without requiring a sense resistor. A strong onboard 1 Ω gate driver minimises switching transient losses associated with driving MOSFETs at high frequency and high voltage. To optimise the size of inductors and capacitors, the switching frequency is selectable from 100 kHz to 1 MHz or can be synchronised to an external source over the same range. The LTC3810 can be configured for pulse skipping operation to maintain high efficiency at light loads. Its 0,8 V reference has ±0,75% accuracy over the operating temperature range of -40°C to +85°C. The adjustable soft-start guarantees safe start-up by eliminating turn-on overshoot, and the device has a tracking feature to control the output voltage during power-up.
