MIC2103/4
75V Synchronous Buck Controllers
Featuring Adaptive ON-Time Control
Features General Description
В® Hyper Speed Control Architecture Enables:
-High Delta V Operation
(VIN = 75V and VOUT = 1.2V)
-Any Capacitorв„ў Stable 4.5V to 75V Input Voltage Adjustable Output Voltage from 0.8V to 24V (Also
Limited by Duty Cycle) 200 kHz to 600 kHz Programmable Switching
Frequency HyperLight LoadВ® Control (MIC2103 Only) Hyper Speed ControlВ® (MIC2104 Only) Enable Input, Power-Good Output Built-In 5V Regulator for Single-Supply Operation Programmable Current-Limit and Fold-Back
“Hiccup” Mode Short-Circuit Protection 5 ms Internal Soft-Start, Internal Compensation,
and Thermal Shutdown Supports Safe Start-Up into a Pre-Biased Output –40°C to +125°C Junction Temperature Range Available in 16-Pin 3 mm x 3 mm QFN Package The MIC2103/4 are constant-frequency, synchronous
buck controllers that feature a unique adaptive ON-time
control architecture. The MIC2103/4 operates over an
input supply range from 4.5V to 75V and can be used
to supply up to 15A of output current. The output
voltage is adjustable down to 0.8V with a guaranteed
accuracy of В±1%. The device operates with
programmable switching frequency from 200 kHz to
600 kHz.
The HyperLight LoadВ® architecture provides the same
high-efficiency and ultra-fast transient response as the
Hyper Speed Control architecture under medium to …
