HA17524 - Switching Regulator Controller

General Description

Principals of HA17524 Operation The HA17524 switching regulator circuit, using pulse width modulation (PWM), is constructed as shown in figure 1.

Timing resistances RT and timing capacitance C T control the oscillation frequency.

CT is charged by a constant current generated by RT .

Key Features

  • Pulse width modulation (PWM) Wide oscillation frequency range: 450 kHz(typ) Low quiescent current: 5 mA typ Good line regulation (0.2% typ) and load regulation (0.4% typ) Independent output stages for 2 channels Wide external circuit.
