GENERAL DESCRIPTION
The ADP2300/ADP2301 are compact, constant-frequency,
current-mode, step-down dc-to-dc regulators with integrated
power MOSFET. The ADP2300/ADP2301 devices run from
input voltages of 3.0 V to 20 V, making them suitable for a wide
range of applications. A precise, low voltage internal reference
makes these devices ideal for generating a regulated output
voltage as low as 0.8 V, with ±2% accuracy, for up to 1.2 A load
current.
There are two frequency options: the ADP2300 runs at 700 kHz,
and the ADP2301 runs at 1.4 MHz. These options allow users to
make decisions based on the trade-off between efficiency and
total solution size. Current-mode control provides fast and stable
line and load transient performance. The ADP2300/ADP2301
devices include internal soft start to prevent inrush current at
power-up. Other key safety features include short-circuit protec-
tion, thermal shutdown (TSD), and input undervoltage lockout
(UVLO). The precision enable pin threshold voltage allows the
ADP2300/ADP2301 to be easily sequenced from other input/
output supplies. It can also be used as a programmable UVLO
input by using a resistive divider.
The ADP2300/ADP2301 are available in a 6-lead TSOT package
and are rated for the ?40°C to +125°C junction temperature range.
