Description
The TS33001/2/3 (1/2/3A) are DC/DC synchronous switching
regulators with fully integrated power switches, internal
compensation, and full fault protection. The switching
frequency of 5MHz enables the use of extremely small filter
components, resulting in smaller board space and reduced
BOM costs.
When the input current is greater than approximately 50mA,
the TS33001/2/3 utilizes PWM voltage mode feedback with input
voltage feed-forward to provide a wide input voltage range
without the need for external compensation.
When the input current is less than 50mA, the device uses a
PFM mode to provide increased efficiency at light loads. The
cross over between PFM mode and PWM is automatic and
has hysteresis to prevent oscillation between the modes.
Additionally, the nLP mode pin can be used to force the device
into PWM mode to reduce the output ripple, if needed.
The TS33001/2/3 integrates a wide range of protection circuitry;
including input supply under-voltage lockout, output undervoltage, output over-voltage, soft start, high side FET and low side
FET current limits, and thermal shutdown.
