The maximum operating frequency of PHP45N03LT is 100 kHz, but it can be used up to 1 MHz with some limitations.
To ensure stability, it's essential to use a minimum output capacitance of 10 μF, and a maximum ESR of 1 Ω. Additionally, the output voltage can be stabilized by adding a 10 nF capacitor between the output and ground.
The maximum power dissipation of PHP45N03LT is 2.5 W, and it's essential to ensure that the device is properly heat-sinked to prevent overheating.
PHP45N03LT is rated for operation up to 150°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to use a heat sink and ensure proper thermal management to prevent overheating.
To protect PHP45N03LT from overvoltage and undervoltage conditions, it's recommended to use a voltage regulator with overvoltage protection (OVP) and undervoltage protection (UVP) features.
