TS30011/12/13
Version 1.6
High Efficiency 1A/2A/3A Current-Mode Synchronous Buck
DC/DC Converter, 1MHz
DESCRIPTION
The TS30011 (1A), TS30012 (2A) and TS30013
(3A) are DC/DC synchronous switching regulator
with fully integrated power switches, internal
compensation, and full fault protection. The
switching frequency of 1MHz enables the use of
small filter components resulting in minimal board
space and reduced BOM costs.
The TS30011/12/13 utilizes current mode feedback
in normal regulation PWM mode. When the
regulator is placed in standby (EN is low), the device
draws less than 10uA quiescent current.
The TS30011/12/13 integrates a wide range of
protection circuitry including input supply under-
voltage lockout, output voltage soft start, current
limit, and thermal shutdown.
The TS30011/12/13 includes supervisory reporting
through the PG (Power Good) open drain output to
interface other components in the system.
