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.
Summary Specification
• Junction operating temperature -40 °C to 125 °C
• Packaged in a 16pin QFN (3x3)
