RT2810A/B
10A, 18V, 500kHz, ACOTTM Synchronous Step-Down Converter
General Description
Features
The RT2810A/B is a synchronous step-down converter
with Advanced Constant On-Time (ACOTTM) mode control.
The ACOTTM provides a very fast transient response with
few external components. The low impedance internal
MOSFET supports high efficiency operation with wide
input voltage range from 4.5V to 18V. The proprietary circuit
of the RT2810A/B enables to support all ceramic
capacitors. The output voltage can be adjustable between
0.7V and 8V. The soft-start is adjustable by an external
capacitor.

Functional Pin Description
Pin No. Pin Name
Pin Function
1 AGND
Analog Ground.
2 FB
Feedback Voltage Input. It is used to regulate the output of the converter to a set
value via an external resistive voltage divider. The feedback reference voltage is
0.7V typically.
3 PVCC
Internal Regulator Output. Connect a 1F capacitor to GND to stabilize output
voltage.
4 RT
An External Timing Resistor Adjusts the Switching Frequency of the Device.
5 SS
Soft-Start Time Setting. An external capacitor should be connected between this
pin and GND.
6 VIN
Power Input. The input voltage range is from 4.5V to 18V. Must bypass with a
suitably large (10F x 2) ceramic capacitor.
7 GND
Ground.
8
PGOOD
Power Good Indicator Open-Drain Output.
9 BOOT
Bootstrap. This capacitor is needed to drive the power switch's gate above the
supply voltage. It is connected between SW and BOOT pins to form a floating
supply across the power switch driver. A 0.1F capacitor is recommended for use.
10 to 14 SW
Switch Node. Connect this pin to an external L-C filter.
15 EN
Enable Control Input. A logic-high enables the converter; a logic-low forces the IC
into shutdown mode reducing the supply current to less than 10A.
16 RLIM
An External Resistor Adjusts the Current Limit of the Device.
