Summary description
The controller is an integrated circuit realized in BCD5 (BiCMOS-DMOS, version 5)
fabrication that provides complete control logic and protection for high performance step-
down DC-DC and niPoL converters.
It is designed to drive N-channel MOSFETs in a synchronous rectified buck topology. The
output voltage of the converter can be precisely regulated down to 600 mV with a maximum
tolerance of ±0.8 % and it is also possible to use an external reference from 0 V to 2.5 V.
The input voltage can range from 1.8 V to 14 V, while the supply voltage can range from
4.5 V to 14 V. High peak current gate drivers provide for fast switching to the external power
section, and the output current can be in excess of 20 A. The PWM duty cycle can range
from 0 % to 100 % with a minimum on-time (T
conversions with very low duty cycle at high switching frequency. The device provides
voltage-mode control that includes a selectable frequency oscillator (250 kHz or 500 kHz).
The error amplifier features a 10 MHz gain-bandwidth-product and 5 V/µs slew-rate that
permits to realize high converter bandwidth for fast transient response. The device monitors
the current by using the R
the need for a current sensing resistor and guaranteeing an effective over-current-protection
in all the application conditions. When necessary, two different current limit protections can
be externally set through two external resistors.
During the soft-start phase a constant current protection is provided while after the soft-start
the device enters in hiccup mode in case of over-current. During the soft-start, the sink
mode capability is disabled in order to allow a proper start-up also in pre-biased output
voltage conditions. After the soft-start the device can sink current. Other features are
power good, master/slave synchronization (with 180° phase shift), over-voltage-protection,
feed-back disconnection and thermal shutdown. The HTSSOP16 package allows the
realization of really compact DC/DC converters.
