General Description
The RTQ2102A and RTQ2102B are 1.5A, high-efficiency,
Advanced Constant-On-Time (ACOT?
) synchronous stepdown converters. The device operates with input
voltages from 3V to 6V. The device can program the
output voltage between 0.45V to VIN. The low quiescent
current design with the integrated low RDS(ON) power
MOSFETs achieves high efficiency over the wide load
range. The advanced COT operation allows transient
responses to be optimized over a wide range of loads,
and output capacitors to efficiently reduce external
component count. The RTQ2102A and RTQ2102B
provide up to 2.7MHz switching frequency to minimize
the size of output inductor and capacitors.
The RTQ2102A and RTQ2102B provide complete
protection functions such as input undervoltage lockout,
output undervoltage protection, overcurrent protection,
and thermal shutdown.
The cycle-by-cycle current limit provides protection
against shorted outputs and soft-start eliminates input
current surge during start-up. The RTQ2102A and
RTQ2102B are available in WDFN-8L 3x3 package.
