TPS65051QRSMRQ1 General Description

To meet the needs of low-noise applications, users can switch the TPS65051-Q1 into fixed-frequency PWM mode by pulling the MODE pin high. In shutdown mode, the current consumption drops to less than 1 μA. Small inductors and capacitors can be used with this device to achieve a compact solution size. With an output current of up to 1 A for DCDC1 and 0.6 A for DCDC2, the TPS65051-Q1 also features two 400-mA LDO and two 200-mA LDO voltage regulators, each with its own enable pin for independent control
