TDK CORP. TDK-Lambda PYH200 series of 200W rated, half brick dc-dc converters. Capable of operating from an ultra-wide 12:1 input voltage of 14 to 160Vdc, units are compatible with 24V, 48V, 72V or 110Vdc nominal system voltages. Products are available with 12V, 15V, 24V or 48V nominal outputs. Using the trim function, devies can be adjusted using a resistor or an external voltage to compensate for voltage drops, or to accommodate non-standard system voltages. Units have latching overvoltage, non-latching (self-recovering) overcurrent and overtemperature protection with adjustable undervoltage control. The hold-up time can be extended up to 30ms with the addition of an electrolytic capacitor connected to the BUS terminal. Product’s switching frequency can be synchronized to an external clock with other PYH200 modules to reduce system noise. Remote on/off is also included as standard. Overall dimensions of the half brick converter are 12.7mm high, 61mm wide and 57.9mm in length.
