Two Monolithic DC/DC Converters Take 3.6VвЂ“15V Inputs
Down to 0.6V at High Frequency, Shrinking Battery-Powered
Applications in Everything from Handhelds to Automobiles
Mylien Tran and Theo Phillips When a relatively high voltage rail (12V) must be stepped down to a relatively low level
(3.3V, 1.8V), the traditional go-to converter is a DC/DC switching controller that drives
external MOSFETs. In many applications, replacing the typical controller-MOSFETdiode combo with a monolithic regulator would save space, design time and cost.
The problem is that 12V rails are too high for many monolithic buck converters, which
usually cannot be used with inputs above 6V. Additionally, switching losses typically
prevent practical operation above ~1MHz, precluding the use of the smallest possible
inductors, and in the end, negating some size advantages of a monolithic regulator.
The LTC3601 and LTC3604 are high
performance monolithic synchronous
step-down regulators capable of supplying up to 1.5A and 2.5A, respectively. They
operate from a wide input voltage range
of 3.6V to 15VвЂ”a range encompassing
battery chemistries found in handheld
devices, PCs, and automobiles. Their
unique constant frequency/controlled on
time architecture has a minimum on-time
of 20ns, ideal for high step-down ratio
applications that demand high switching
frequencies and fast transient response
while maintaining high efficiency. …
