Introduction The “Type B” regulators (R600B and R400B) do not require
The LTC3562 quad output step-down regulator is designed external programming resistors because the resistors are
for multicore handheld microprocessor applications that integrated on-chip. The values of the internal feedback
operate from a single Li-Ion battery. Its four monolithic, high resistors are adjusted through the I2C port, resulting in
