LT8471HFE#PBF

LT8471 is a dual PWM DC/DC converter containing two internal 2A, 50V switches and an additional 500mA switch to facilitate step-down and inverting conversion. Each 2A channel can be independently configured as a buck, boost, SEPIC, flyback or inverting converter. Capable of generating positive and negative outputs from a single input rail, this device is ideal for many local power supply designs. This device has an adjustable oscillator, set by a resistor placed from the RT pin to ground. Additionally, this device can be synchronized to an external clock. The free running or synchronized switching frequency range of the part can be set between 100KHz and 2MHz. It is widely used in application such as dual rail power for signal chain, buck/buck, buck/boost, boost/boost, boost/invert, invert/invert, buck/invert etc.

• Wide input voltage range is 2.6V to 50V
• UVLO and OVLO programmable on OV/UV pin
• Soft-start programmable for each channel
• Fixed frequency PWM (set by RT pin or synchronized to external clock)
• Anti-phase switching reduces input ripple
• 500mA skyhook channel efficiently generates boosted input voltage
• Operating temperature is -40°C to 150°C
• Packaging style is 20-lead plastic TSSOP
