MCP19035
High-Speed Synchronous Buck Controller
Features: General Description Input Voltage Range: from 4.5V to 30V Targeted for Low-Voltage Power Trains with
Output Current up to 20A High-Speed Voltage Mode, Analog Pulse-Width
Modulation Control Power Good Output Internal Oscillator, Reference Voltage and
Overcurrent Limit Threshold for Stand-Alone
Applications. Multiple Switching Frequency Options (FSW):
-300 kHz
-600 kHz Integrated Synchronous MOSFET Drivers Multiple Dead-Time Options Internal Blocking Device for Bootstrap Circuit Integrated Current Sense Capability for Short
Circuit Protection Internal Overtemperature Protection Under Voltage Lockout (UVLO) Integrated Linear Voltage Regulator 10-LD 3 X 3 mm DFN Package The MCP19035 is an application-optimized, highspeed synchronous buck controller that operates from
input voltage sources up to 30V. This controller
implements a voltage-mode control architecture with a
fixed switching frequency of 300 kHz or 600 kHz. The
high-switching frequency facilitates the use of smaller
passive components, including the inductor and
input/output capacitors, allowing a compact, highperformance power supply solution. The MCP19035
implements an adaptive anti-cross conduction scheme
to prevent shoot-through in the external power
MOSFETs. Furthermore, the MCP19035 offers multiple
dead-time options, enabling an additional degree of
optimization, allowing a higher efficiency power supply
design. Applications: Point of Loads
