概述

The TPP15053 is a wide input range, non-synchronous DC-DC buck converter that uses peak current mode control. The TPP15053 integrates a 170-V, 1.3-Ω power MOSFET with 1.5-A peak current limit having up to 0.5-A output current capability.

The TPP15053 has a high-voltage startup circuitry to enable the device from high input voltage directly. The TPP15053 has a built-in 12-ms soft-start time to minimize the inrush current during startup. In the moderate to heavy load condition, the TPP15053 works in PWM mode at 100-kHz switching frequency. In the light load condition, the TPP15053 enters PFM mode to reduce the switching loss and improve the efficiency. The TPP15053 also has spread spectrum switching frequency dithering to reduce the EMI.

The TPP15053 features a cycle-by-cycle current limit in over-load conditions. Furthermore, when the output voltage is 10% below the regulation target and the current limit is touched for 128 switching cycles, or the output is short to ground, the TPP15053 enters hiccup mode and stops PWM switching for 65 ms. After hiccup times out, the TPP15053 restarts the soft startup.

The TPP15053 is available in the SOP8 package.
