Product Overview
LTC3810-5 is a synchronous step-down switching regulator controller that can directly step-down voltages from upto 60V, making it ideal for telecom and automotive applications. It uses a constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit, without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifier provides very fast line and load transient response. Large 1 ohm gate drivers allow the device to drive multiple MOSFETs for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN and can also be synchronized to an external clock for switching-noise sensitive applications. It is used in application such as 48V telecom and base station power supplies, networking equipment, servers, automotive and industrial control systems etc.
- No current sense resistor required, dual N-channel MOSFET synchronous drive
- Programmable output voltage tracking/soft-start
- Generates 5.5V driver supply from input supply
- Synchronizable to external clock, selectable pulse skip mode operation
- Power good output voltage monitor, output overvoltage protection
- Adjustable cycle-by-cycle current limit, programmable undervoltage lockout
- INTVCC supply current is 3mA typical at (SHDN > 1.5V, TA = 25°C)
- INTVCC shutdown current is 240µA typical at (SHDN = 0V, TA = 25°C)
- Operating junction temperature is -40°C to 125°C
- Package style is 32-lead plastic QFN
