The PQ1CG21H2RZH is a low-power DC-DC switching regulator from Mitsubishi Electric intended for use as a point-of-load converter in a wide variety of power applications. It offers flexibility, stability, and efficiency in a small size package. With a switching frequency of up to 1 MHz, it enables faster turn-on times and reduced power consumption.

The PQ1CG21H2RZH is a synchronous buck regulator and is specifically designed to regulate a current by switching the power MOSFETs between the input and output sides of the DC-DC converter circuit. The device can control output voltage between 0.6V to 4.5V and outputs up to 1.5A. It is available in a QSOP-8 package for circuit board mounting.

The PQ1CG21H2RZH features dual mode operation with either Pulse Frequency Modulation (PFM) or Burst Mode Control (BMC). In PFM mode, the device runs in a low frequency operation which results in increased efficiency at light loads and low power consumption. In BMC mode, it runs in high frequency operation which increases efficiency at loads of up to 1.5A. In addition, the device has various protection features such as undervoltage lockout (UVLO), short circuit protection (SCP), and over temperature protection (OTP).

The PQ1CG21H2RZH is suitable for use in a wide range of applications including industrial and telecom systems, LCD and LED displays, servers, FPGA\'s, gaming systems, automotive and medical devices, and many more. It is also ideal for applications which require low noise operation and require low power consumption.

The PQ1CG21H2RZH provides flexible output control with a wide range of voltage control options, allowing the user to select the best setting for their application needs. In addition, the PQ1CG21H2RZH features external synchronization which allows for synchronization of multiple devices to operate with a single clock. This provides lower output ripple and improved system performance.

The PQ1CG21H2RZH is a DC-DC switching regulator that offer a wide range of features and flexibility for demanding power applications. With its dual mode operation, protection features, and adjustable control options, the device is an ideal choice for a variety of power conversion applications.
