Product Overview

LT8710 is a synchronous PWM DC/DC controller with a rail-to-rail output current monitor and control. It is ideal for many types of power supply topologies and can be easily configured for boost, SEPIC, inverting, or flyback configurations. This device’s rail-to-rail output current monitor and control allows the part to be configured in current limited applications such as battery charging. The FLAG pin can be used as a power good indication or C/10 indication allowing for accurate bulk and float battery voltages. It also features innovative EN/FBIN pin circuitry that allows for slowly varying input signals and an adjustable undervoltage lockout function. The pin is also used for input voltage regulation to avoid collapsing a high impedance input supply. It is used in applications such as high power local power supply, wide input voltage range SEPIC/inverting, lead acid battery charger, automotive engine control unit (ECU) power, solar panel power converter etc.
  • Wide input voltage range is 4.5V to 80V
  • Input voltage regulation for high impedance inputs
  • MODE pin for forced CCM or pulse-skipping operation
  • Can be synchronized to external clock
  • High gain EN/FBIN pin accepts slowly varying input signals
  • Switching frequency is 750KHz typical at (RT = 46.4K, TA = 25°C, VIN = 12V)
  • Quiescent current is 4mA typical at (VBIAS = VISN = 7.5V, not switching, TA = 25°C, VIN = 12V)
  • Quiescent current in shutdown is 1µA maximum at (VEN/FBIN = 0V, TA = 25°C, VIN = 12V)
  • Operating junction temperature is -40°C to 125°C
  • Package style is 20-lead plastic TSSOP
