ROHM's low quiescent current DCDCs for Automotive

ROHM's BD9901x Family is a synchronous buck converter series that integrates low resistances MOSFETs. It achieves a continuous output current of 2A over a wide input supply range. The SLLMTM (Simple Light Load Mode) control ensures an ultra low quiescent current and high efficiency at low load situation as well as a high efficiency at high load situations while maintaining a regulated output voltage. The product is compliant with automotive standards and accommodates a maximum voltage of 42V. The minimum input voltage is 3.6 V in order to sustain output at cold cranking conditions. The current mode regulation loop gives a fast transient response and easy phase compensation.

Features:

Input Voltage Range: 3.6V to 42V
Output Voltage: 3.3V or 5.0V
Output Current: 2.0A
Switching Frequency: 200 to 500kHz (typ.)
High Efficiency
Low Quiescent Current: typ. 22µA over temperature range (-40 to 105°C)
Integrated Power MOSFETs for synchronous rectification (High side p-type and low side n-type)
Integrated Feedback Resistors
Fixed Soft Start Time (typ. 6ms)
Int. Protection Function: OCP, SCP, TSD, UVLO, OVP

Applications:

BD9901x Low IQ DC/DC Converters are AEC-Q100 qualified. Ideal for use in Automotive Battery Powered Supplies (Cluster Panel, Car Multimedia).
